A broadband optical detector is disposed to measure the total intensity I( lambda , alpha ) attributed to a portion of the optical spectrum passed by a sharp bandgap optical transmission element as the bandgap is caused to translate over a desired wavelength interval by a band gap control parameter, T. The differential spectrum of the incident optical radiation is recovered by the differentiation of I( lambda , alpha ) in respect to the parameter T.
