Abstract
A spectrometer for use with optical elements which pass both undispersed and dispersed irradiation onto detectors coupled to a transversal filter and a comparitor means which open gates said filter to receive dispersed signals when an initial undispersed threshold is exceeded, thereafter said comparitor inhibits signals exceeding the undispersed threshold during spectral analysis of the dispersed signals.
