Abstract
SCD has established an uncooled detector product line based on the high-end VOx 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.
