本文提出了一种1280×720分辨率的单光子检测图像传感器,采用灵敏度增强技术实现了100dB的动态范围,解决了在极低光照条件下(如新月照度)单光子检测的难题,同时保持了常规CMOS像素尺寸(1.5-5μm)。
sensors such as camcorders, digital still cameras, mobile phones, and surveillance cameras. Even though leading-edge image sensors have reached the noise floor of a few electrons [1,2], a thrust towards darker levels still continues down to an illumination level equivalent to being under a crescent moon (i.e., 10-2 down to 10-4 lux). This requires single-photon detection with typical digital cameras pixel size, i.e., 1.5 to 5μm. Although huge-size pixel [3] or single-photon avalanche photodiode (SPAD) based image sensors [4] have been presented for such a purpose, in general, both have to pay area and dark current penalties. Thus, an image sensor capable of both single-photon detection and normal imaging providing us with a high dynamic range is a huge technological challenge.
