PtSi焦平面列阵的现状PtSi于1991年以1040×1040元的列阵率先实现了兆象元数的红外敏感器规格,从技术上来看,1024×1024依然是已演示的最大的红外敏感器规格。该敏感器芯片将读出部分和探测器合并成单片结构,其象元中心间距为17μm。红外敏感面积的占空因子为53％。大部分其它类型的Ptsi列阵也都是单片结构,其填空因子在50％和80％之间,这取决于象元尺寸以及象元基本单元内光敏面积与帧时间内甩于信号积分的电荷存 PtSi focal plane array status PtSi in 1991 to 1040 × 1040 yuan array first to achieve the megacycles infrared sensor specifications, from a technical point of view, 1024 × 1024 is still the largest demonstration of the infrared sensor specification. The sensor chip combines the sensing part with the detector into a monolithic structure with a pixel center pitch of 17μm. The duty factor of the IR sensitive area is 53%. Most other types of Ptsi arrays are also monolithic with a fill factor of between 50% and 80%, depending on the pixel size and the photo-sensitive area in the base unit of the pixel and the signal integration in the frame time Charge storage
