Abstract

InGaAs detector can be used as the image sensor in SWIR (Shortwave Infrared) band as. Cameras with InGaAs detector have been widely used in the astronomical observation field. Based on the optical band CCD camera readout technologies that we have mastered, this paper introduced one China domestic InGaAs detector, and proposed this camera readout system with it, which includes the whole circuits structure, pixel transferring timing and image acquisition method. We summarized these technologies, presented the appropriate solutions and the simulation results as well. These works provide technical support to develop infrared scientific camera
