ABSTRACT:
Disclosed are an optical test apparatus, related test method and method of operation, and related probe card adapted to optically test an image sensor. An illumination source of the optical test apparatus provides an optical test signal to the image sensor through the probe card. The optical test signal has a property variably defined by a feedback loop formed between a reference image sensor associated with the probe card and a control unit connected between the reference image sensor and the illumination source.
