A researcher in optical measurement whose work with Jeanne M. Houston establishes detector spectral responsivity. A detector’s electrical signal is compared with a calibrated reference while the illumination wavelength is varied; subtracting dark current and monitoring source changes separates optical response from instrumental offsets. The resulting calibration converts a measured current into optical power, with an explicit dependence on wavelength rather than a single sensitivity number.[ref]
