Abstract :
A fully functional instrumentation for electro-optical characterization of silicon photodetectors is presented. The system is intended for laboratory use where typically a few devices are characterized at a time. The instrument is designed for determining the spectral, spatial and temporal photoresponse of a single photodetector or a photodetector array. Also Geiger mode detectors can be tested. In case of photodetector arrays fast determination of modulation transfer function and photoresponse nonuniformity is possible. The instrument setup and experimental results are presented.
