→ MATRIX organisation

Tests ProgramTests Program

→ Tests Program Focus : promote and market the space validation and environmental testing capabilities of CSL

Environmental tests

qualification of space hardware : overall system survival and performance demonstrated during and after exposure to simulated flight/space conditions

→ thermal vacumm qualification (down to cryogenic temperatures)

→ vibration qualification

validation of modelling from combined analysis and test

identification of workmanship and material defects

Also included in the CSL test service package:

•decontamination and contamination monitoring•test set-up design and manufacturing•review of test feasibility and specifications•test plan and test procedure•Assembly, Integration and Verification (AIV) operations•mechanical, thermal and optical expertise•result analysis and reporting…

2.2.Strategy for Organic/Non Organic Strategy for Organic/Non Organic

Discrimination Based on Discrimination Based on Remotely-Sensed DataRemotely-Sensed Data

Tool 1 : Satellite/Aircraft/UAV Measurements

Identify indicators (e.g. spectral) for organic/non-organic discrimination

• Images• Field measurements

Define and implement image processing system

Extended validationa and consolidation

Operationalisation

Tool 2 : Field Measurements

Specify and design portable field spectrometer tailored to organic certification

3.3.Specific CapabilitiesSpecific Capabilities

Optical Design & Metrology Optical Design & Metrology

• development of Optical Ground Support Equipment (qualification for space environment)

• prototyping : development of new metrology tools and of flight metrology instrumentation

• R&D support in metrology problems and optical field (sensors, image acquisition, illumination devices, spectral analysis)

• optical design and analysis (eg. stray light analysis, study of optical function working in severe

environment)

• simulations, optimization (CODE V, ASAP, FRED, IDL or

Intelliwave)

Example of Technology Transfer in Optics : theoretical design of an artificial intraocular lens to treat cataract (left) and actual lens (right)
