Focal plane illuminator for generalized photon transfer characterization of image sensor

摘要

A method and apparatus for characterizing a pixel of an image sensor is provided. The apparatus includes a narrowband, temporally incoherent, temporally stable illumination source. The narrowband light source generates a spatially coherent illumination beam. A variable optical attenuator attenuates the illumination beam resulting in an attenuated beam that does not alter the uniformity of the illumination. A focal plane integrator projects, expands, and homogenizes the attenuated beam to illuminate a focal plane of a sensor. Image sequences are collected to generate statistics for characterizing the sensor.
