Last year SCD presented an un-cooled detector product line based on the high-end VO x microbolometer technology. The first PFA (BIRD384) launched was a 384x288 software configurable (to 320x240 or other) format with 25µm pitch 1 . NETD values for these FPAs are better then 50mK with an F/1 aperture and 60 Hz frame rate. Since then SCD has concentrated in improving both spatial and temporal performance. In order to reduce the Residual Non-Uniformity (RNU) and increase the time span between shutter operations, SCD has incorporated various features within the FPA and supporting algorithms 2 . Improved temporal performance was achieved by optimizing concurrently the membrane structure and ROIC electronics. SCD has demonstrated temporal NETD of ~ 20mK @ F/1 at 30Hz on a 160x120 BIRD compatible array. This figure of merit, accompanied by the superior stability and reduced power consumption, makes SCD's VOx based detectors suitable candidates for a broad range of "high-end" military and commercial applications.

SCD has established an uncooled detector product line based on the high-end VO x µ-bolometer technology. The first PFA launched was BIRD384, a 384x288 (or 320x240) configurable format with 25µm pitch. Typical NETD values for these FPAs are below 50mK with an F/1 aperture and 60 Hz frame rate. The product exhibits superior image uniformity, stability and reduced power consumption, making it most suitable for a broad range of "high-end" military and commercial applications. In this paper we report on our progress in development of new products in accordance with SCD's uncooled products roadmap: 1. A "sensitive" version of BIRD384 with an improved NETD of ~ 30mK @ F/1, 60Hz frame rate. This performance is achieved by optimizing concurrently the membrane structure, pixel architecture and ROIC electronics. 2. An improved version of BIRD384 ROIC that supports 100/120Hz frame rate and high dynamic range ("Fire Man" option). 3. First data of the BIRD640 -a 640x480 array with 25µm pitch and NETD ≤ 50mK @ F/1, 60Hz frame rate.
