Abstract
A method for use with a light-sensitive integrated circuit includes applying different wavelengths of light to the integrated circuit to produce output signals in response to the different wavelengths of light, measuring the output signals to obtain measured values, comparing the measured values to setpoint values that correspond to the different wavelengths of light, obtaining correction values for the different wavelengths of light that are based on the comparison, and storing the correction values on the integrated circuit.
