Abstract

The high level of accumulated expertise by ULIS on uncooled microbolometers TEC-less operation enables ULIS to develop 384 x 288 (1/4 VGA) IRFPA format with 25μm pixel-pitch especially designed for TEC-less application. This detector, while keeping all the performances and all the innovations developed on previous ULIS ROIC (NETD performance, detector configuration by serial link, low power consumption and wide electrical dynamic range ...), can be operated on a wide range of ambient temperature, with constant settings. We present in this paper the electro-optical performances and the TEC-less capability of this device. The thermal behavior is described in detail.
