摘　　要：报道了64×64 元GaAs/AlGaAs 多量子阱凝视型红外焦平面的研制,器件的平均响应率为RP= 7.24×105V/W,器件的平均黑体探测率为Db = 5.40×108cm ·Hz1/2/W ,峰值波长为λP= 8.2μm ,不均匀性小于20% 。A staring infrared FPA of 64×64 multiple quantum wells (MQW) was developed. The average responsivity R p =7.24×10 5V/W was obtained with the peak wavelength λ p =8.2μm. By the typical blackbody detectivity definition of FPAs, the average detectivity was D * b =5.40×10 8cm·Hz 1/2 /W. The non uniformity was smaller than 20%. Finally, a distinguished thermal image of a room temperature body was obtained.
