  • light means for selectively exposing said device to light from a source;

    means for determining a temperature dependent electrical characteristic of said device that is independent of said light characteristic; and

    temperature compensating means that produces in response to said light response signal and said device electrical characteristic a detector output that corresponds to said light characteristic and that is compensated for operating temperature of said device.
