A simple system for optical spectra monitoring and measurement for both continuous and pulsed laser emission is presented. The system consists of Fary-Perot interferometer with constant inter-mirror distance, simple CCTV (closed circuit television) camera, sampling unit, multichannel analizer and microcomputer. Interferograms of either single or multiple pulses are recorded and averaged digitally and then processed numerically to yield parameters of spectral distribution.
