LYNRED is a global leader in designing and manufacturing high quality infrared technologies for aerospace, defence and commercial markets. Its vast portfolio of infrared detectors covers the entire electromagnetic spectrum from near to very far infrared, especially thanks to well-mastered wavelength tuneable MCT technology. In addition, space radiation resilience of MCT technology enables LYNRED to be the leading European manufacturer for IR detectors deployed in space. One noticeable recent trend associated to space detectors market is the increase of requested multilinear/multispectral array format (from around 1000 up to 4000 photo-elements) combined with a high frame rate need (frame time from 100µs up to several hundred of µs). However, these characteristics are generally not compatible with the current windowed 2D-large sensors off-the-shelf offer of space market especially due to technical different operating points between 2D and linear sensors. Therefore, specific recent developments have been triggered by LYNRED in order to better suit future pushbroom (generally based on several multilinear arrays) or whiskbroom (generally based on one multilinear array) instrument concepts. One of the main challenges of this portfolio extension is to design a multilinear sensor space product line not only based on space proven building blocks heritage but also on delayed differentiation approach as much as possible. This design orientation will enable to fit optimally to the widest range of space instruments needs in a reduced time. First of all, multilinear/multispectral sensors development is based on two pillars addressing two segments of applications in terms of flux and spectral ranges. Even if the segmentation of space application for multilinear sensor is not strictly binary, the first segment concerns Low Flux applications (named LF) whereas the second one is dedicated to High Flux (named HF). LF applications being mainly dedicated to SWIR and MWIR spectral range and HF applications oriented to space applications from MWIR up to VLWIR spectral range. The first chapter will focus on the input technical requirements for both segments and on the discussion of the main associated design challenges.
