ABSTRACT for online preview (<100 words)

Cooled IR technologies are challenged for answering new system needs like compactness and reduction of cryo-power which is key feature for the SWaP (Size, Weight and Power) requirements.
Sofradir has improved its HgCdTe technology to open the way for High Operating Temperature systems that release the Stirling cooler engine power consumption.
A compact 640×512 15µm pitch MW detector presenting high EO performance above 150K with cut-off wavelength above 5.0µm will be discussed.
The ongoing development and results on small pitch detector for SWaP systems will also be discussed, to address high performance compact systems with no compromise on detector resolution.

 

ABSTRACT for technical Review (<250 words)

Cooled IR technologies are challenged for answering new system needs like the compactness and the reduction of cryo-power which is a key feature for the SWaP (Size, Weight and Power) requirements.
Over the last years, Sofradir has improved its HgCdTe technology, with effect on dark current reduction, that opens the way for High Operating Temperature (HOT) systems that can get rid of the 80K temperature constraint, and therefore releases the Stirling cooler engine power consumption.
A compact 640×512 15µm pitch MW detector presenting high EO performance above 150K with cut-off wavelength above 5.0µm has been developed. Its different performances with respect to the market requirements for SWaP will be discussed.
High performance compact systems will make no compromise on detector resolution. The pixel pitch reduction is the answer for resolution enhancement with size reduction. We will therefore also discuss the ongoing development and results on small pitch detector for SWaP systems.

 

BRIEF BIOGRAPHY

Alain MANISSADJIAN graduated in Physics and Optics from Ecole Nationale Supérieure de Physique de MARSEILLE (France) in 1990. He carried out optronic equipments development at THALES OPTRONIQUE S.A. (France) in 1991, and was a research assistant in SiGe photoluminescence at UCLA Electrical Engineering Dept. (Los Angeles, USA) in 1992-1993. He joined SOFRADIR in 1993 as a development engineer and then he has been working as a project engineer since 1996 and as a development program manager since 2002.
