  • Patent number: 4061925
    Abstract: An apparatus for testing the optical output of light-emitting devices in the presence of ambient light, with means for compensating for said ambient light, is described. The d.c. and periodic components of the ambient light are measured and stored during a time when the apparatus is not being subjected to radiation from the device under test (DUT). When radiation from the DUT is received, the resulting signal is processed with the stored ambient light intensity data, and an output proportional to the intensity of the radiation from the DUT and compensated for the ambient light is provided.
