Abstract

An instrument for performing optical tests on infrared photodiodes has been designed and tested. This instrument uses Pb-salt tunable diode lasers as a source and can record spatial sensitivity maps of detector elements, temporal response to fast pulses, and spatial maps of the temporal response as well as uniformly illuminate large area detector arrays. The spatial maps presented demonstrate a spatial resolution of 100 Tim. The pulse data presented indicates that the optical risetime of these Pb-salt lasers is less than 500 ps for pulses of 1, 10, or 100 ns duration.
