A solid-state image sensor for image recording at 2000 frames per second

We describe a solid-state sensor for image recording at frame rates up to 2000 full or 12 000 partial frames per second (fps). The sensor consists of a 192 V × 248 H array of photocapacitors. For high-speed operation the image-sensing area is divided into 6 blocks, each with 32 parallel outputs. The blocks are addressed sequentially, and the 32 outputs are sensed simultaneously. The sensor dynamic range is 46 dB at 2000 fps. Data on sensor speed, spectral sensitivity, noise, and spatial resolution are presented and compared with those of models.
