洛克威尔国际公司导弹系统分部已研制成一个外场便携式红外成象器,能够以60Hz速率获得128×128和256×256图象。系统已成功地对各种地面目标和机载战术目标进行了演示。所用的凝视列阵是工作在4.4～4.85μm范围的中波红外碲镉汞混合器件。多路开关是采用硅,并且是一个CMOS FET转换FET器件,列阵封装在实验室用的杜瓦瓶内,在80K下工作,而相应噪声等效温差(NETD)为0.03K。列阵在室温和80K之间已进行了热循环40次以上。系统的光学部分是由一个f/数=2和通光孔径为20.32cm的透镜组成,对128×128瞬时视场为0.29mrad,而256×256瞬时视场为0.2mrad,成象器积分时间从最小1.626ms变到3.352ms。
Rockwell International Missile Systems Division has developed an outfield portable infrared imager capable of obtaining 128 x 128 and 256 x 256 images at 60 Hz. The system has successfully demonstrated various ground targets and airborne tactical targets. The gaze array used is a mid-wave infrared HgCdTe hybrid device operating in the range of 4.4-4.8 [mu] m. The multiplexer is silicon and is a CMOS FET switching FET device. The array is packaged in a laboratory dewar for operation at 80K, with a corresponding NETD of 0.03K. The array has been thermally cycled 40 times or more between room temperature and 80K. The optical part of the system consists of a lens with f / number = 2 and a clear aperture of 20.32 cm, with an instantaneous field of view of 128 x 128 at 0.29 mrad and an instantaneous field of view of 256 x 256 at 0.2 mrad, From the smallest 1.626ms change to 3.352ms.
