“…Dual-band QWIP implementations like [85,86] extend vision capabilities to bispectral M/LWIR vision applications. Low-cost IR imaging solutions are mostly based on monolithic VOx [87,88] or a-Si [89][90][91] microbolometers thermal approaches, and avoid any incorporation of external cooling mechanisms. Common trend is to move ROIC designs to the digital domain performing A/D conversion either at column or pixel stages.…”

“…The electrical noise increases at lower frequencies is due to the increasing contribution of 1/f -noise [3]. Several IR sensitive materials have been used in uncooled IR detection, including vanadium oxide (VOx) [7]- [9], a:Si [10]- [17], Yttrium-Barium-Copper-Oxide (YBaCuO) [2], [18], [19], Silicon Germanium (SiGe) [20], Silicon Germanium Oxide (Si-Ge-O) [21]- [28], metals [29], [30] and poly:SiGe [3], [31] (see table I). Vanadium Oxide (VOx) and amorphous silicon (a:Si) technology have comparable performance.…”

“…Low-cost thermal imaging is dominated by uncooled infrared focal plane arrays (IRFPAs) using microbolometers based on vanadium oxide (Blackwell et al, 2008) or amorphous silicon (Durand et al, 2009) as the sensing material. According to Plank's law, each body with a temperature above absolute zero point emits electro-magnetic radiation.…”
