Space Optics Instrument Design & Technology 2022
8 May - 13 May 2022
Poltu Quatu, Sardinia
Due to the covid-19 pandemia the course on Space Optics Instrument Technology had to be shifted from 2020 to spring 2022.
After two years work in home office and under lock-down conditions it was for many participants the first time working under normal conditions, meeting colleagues personally and discussing face to face. The course was a great success.
About the course
The European Space Agency took in 2015 the initiative to organize a course for professionals operating in the sector of optical engineering for Space. Two types of courses are organized: one dedicated to space optics instrument design and the other space optics instrument technology. The two courses are organised alternatively, one per year. The course of 2020 is targeted to space optics technology.
The team of lecturers consists of professionals with a long standing experience in the sector. Their accessibility during the course, gives the participants a unique opportunity to deepen their knowledge with one-to-one meetings aside of the planned lectures.
The venue hosting students and lecturers gives plenty of opportunities to develop a professional network. Sharing problems and discussing solutions together is the way to build a community of space optical engineers enabling and fostering growth in the space sector as a whole.
The contracted venue is again the Grand Hotel Poltu Quatu, close to Olbia – Sardinia (Italy) http://www.poltu-quatu.com/en/index.php.
Keywords: course, space, optical design, freeform surfaces, optical technologies, optical engineering, ZEMAX, Optics Studio, Optical manufacturing technology, metal optics, diamond micro-machining, optical design, optical verification, telescope alignment, grating technology, detector, polarization scrambler, slit homogenizer, stressfree optical mounting, cubesat, hyperspectral imager

Course Overview and Schedule
The 2022 course will present state-of-the-art technologies for space optical instruments providing an overview of new design, manufacturing and integration technologies. Besides other topics, there will be lectures on the new area of freeform design, definition, optimization, tolerancing and verification, as well as how to implement this in optical design software. The rapidly growing field of optical CubeSat technology will also be addressed.
The course will be organised into two parallel classes. Class B is for optical engineers, familiar with optical design and sequential optical design analysis, while class A is intended for engineers with less experience in optical engineering and design or with a different background and expertise. In class B there will be a dedicated lecture on advanced CodeV freeform definition and optimization of optical instruments. Class A and B will differ in content only for the lectures on Monday and Tuesday.

Introduction to CodeV
This lecture will be a hands-on induction to CodeV optimization and tolerancing analysis features. After a short introduction to CodeV, we will discuss optimization techniques and apply them to simple optical systems (singlet, doublet). We will then cover the basic of tolerancing theory and its implementation within CodeV. Finally, we will present desensitization techniques and an inverse tolerancing example.
Freeform design optimization with CodeV
Freeform surfaces can represent an efficient solution to reduce system’s aberrations, while offering at the same time significant benefits and cost savings. In this lecture, we will briefly introduce freeforms and discuss the models available in CodeV.

The lecture focuses on technologies needed to realize metal optics for applications ranging from XUV to IR and discusses the advantages and disadvantages of metallic mirror substrates within space instruments. A major emphasis is put on techniques required to realize freeform optics in metallic substrates, namely diamond micromachining and sub-aperture polishing processes, ultra-precise mechanical references and integrated metrology fiducials, and snap-together system concepts. Finally, guidelines and hints for the design and fabrication of metal optical systems will be given on the hand of past and current space missions.

Polarization Scrambler and slit homogenizer technology – Jerome Caron
Polarization scramblers are optical devices that depolarize light and alter as little as possible light propagation so that they can be used in imaging instruments. Spatial pseudo-depolarizers [1] are compact and passive scramblers with high performance that are well suited for space, and are or have been used in several spectro-imagers to make the measurements insensitive to polarization. In this course we will present their design, performance, manufacturing and testing.

In imaging spectrometers a telescope images a ground scene onto the entrance slit of a spectrometer. Patches of clouds, snow or ground albedo variations create a non-homogeneous slit illumination that results in spectral distortions. Slit homogenizers provide an elegant hardware correction of this effect. They are promising components that have been recently designed for Sentinel-5. We will discuss their design, performance and manufacturing.

Optics packaging Technologies for harsh environment – Erik Beckert
Not only the design, but also the packaging of optical systems is a key factor for highly performant and reliable, robust systems. This is of interest in particular in harsh environments, such as aviation and space, but also vacuum science and high power laser machining. Packaging of optical systems poses various challenges – different materials have to be joined together, components and their optical performance are stress and alignment sensitive, heat from active sources and conversion materials needs to be dissipated, and steep temperature gradients causing thermomechanical stress can occur. Well designed and optimized packaging and bonding technologies address these needs.
The talk will focus on bonding techniques for metallic and non-metallic, amorphous and crystalline materials, emphasizing on the development and application chain from bonding geometry design, optimization by simulation of stress and the resulting birefringent or laser-optical performance, and practical issues of processing and equipment when applying different bonding technologies. Specific technologies to be discussed are gluing, soft soldering by means of laser reflow, hydrophilic bonding and plasma assisted bonding as well as two-photon absorption based laser welding. The basics as well as design and parametrization of these techniques will be discussed, followed up by boundary conditions and restrictions. Examples will demonstrate the application of the different technologies in reality. Amongst them is the green laser for the Raman experiment of the upcoming 2020 ExoMars Mission, a nanosecond fiber laser for a space LIDAR and an entangled photon source for a satellite quantum payload.

AIT of On- and Off-axis telescopes – Matthias Erdmann
The optical alignment of the telescope is a key activity of the AIT process of On- and Off-axis telescopes. The method described and practiced in the lecture is based on the fact that any alignment activity (shifting and tilting of optical elements) influences only the low order aberrations of the optical system. For the alignment the Wave Front Error (WFE) of the telescope is measured (e.g. by auto-collimation) and decomposed in low order aberration contributions. Based on analysis of the as-built model of the telescope and probing of the pre-aligned telescope optics sensitivities of low order WFE contributions to all optical alignment Degree Of Freedoms can be evaluated. Based on these sensitivities the next step of alignment improvement can be calculated, executed and verified. Recursive application of these technique converges to a perfect optical alignment after two or three iterations. For Korsch type telescopes including Three Mirror Anastigmats (TMA) the typical aberration and aberration sensitivities field gradients are discussed and their utilisation for the alignment is described and practiced.

Innovation and Technology Management in Space Optics – Luca Maresi
The shelves of bookstores are full with a wide variety of books on innovation. The pace of technology innovation in consumer products is breathtaking. High-tech start-up pops up every day, and established companies struggle to keep with the pace of technology evolution.
In the Space business, the effort for qualifying and space testing new technologies slow down the technology refresh time. However, Space has been experiencing quite an acceleration in innovation thanks to small satellites and, more recently, cubesat. These provides a lower cost and a faster access to Space. However, a careful selection of new technologies and a thorough verification is still needed to ensure that the hardware will functions properly once in Space.
For both small satellites, and large space infrastructures, even if done at difference level the use of innovative concepts is always a trade-off between risks, delivery time and costs.
The first part of the lecture provides an introduction of the Innovation and Technology Management processes presenting study cases for the commercial market. The second part of the lecture focuses on the processes used in Space. Examples and real-life experience are presented. The lecture concludes with some considerations on how Innovation and Technology Management Processes shall be adapted in the current technology landscape in Space Optics.
