Abstract
A system for measuring an optical spectral response of a photoelectric DUT includes a spectrally programmable light source including a broadband light source, a dispersive element for dispersing the light, and a spatial light modulator for controlling an intensity and a spectra of the light to provide a spectrally programmable light beam. A light distributing device is coupled to receive the spectrally programmable light beam and includes a light distributing structure for distributing the spectrally programmable light beam in a known ratio to a first area and a second area. A reference detector is positioned at the first area, and the DUT is positioned at the second area. Data acquisition electronics and a processor receive simultaneously generated output signals from the DUT and the reference detector to correct for intensity variation in the spectrally programmable light beam in determining the optical spectral response of the DUT.
