Abstract
There is herein disclosed a laser detector and spectral analyzer comprising a plurality of photoelectric detector elements, at least, two of which are suitably masked and disposed behind a wedge type interference filter. An additional detector element is operated without any mask or filter. The detector output signals are electronically processed to provide a substantially instantaneous and independent indication of the mean spectral wavelength, spectral width, total power and pulse length of radiant energy incident upon the apparatus.
