Paper Abstract

The high level of accumulated expertise by ULIS and CEA/LETI on uncooled microbolometers made from amorphous silicon layer enables ULIS to develop 384 × 288 (1/4 VGA) IRFPA formats with 25 μm pixel-pitch designed for high end applications. This detector ROIC design relies on the same architecture as the full TV format ROIC one (detector configuration by serial link, user defined amplifier gain, windowing capability ...). The detector package is identical as the 384 × 288 / 35 μm and 640 × 480 / 25μm ones, enabling an easier system update or less non recurrent cost for different systems developments. This paper will give results of the IRFPA characterization. NETD in the range of 30mK (f/1, 300 K, 60 Hz) and operability higher than 99.99 % are routinely achieved.
