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 pitch¹. 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 algorithms². 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.
