The author proposed a technique for measuring the statistical distribution spectrums of scintillation, beam spread and of spot dancing. The main concepts are that the intensity of laser beam is directly converted into the amplitude of photoelectric pulse and fed to a multichannel analyzer. And by using the beam width (or displacement)--time--amplitude conversion technique the statistical spectrums will be determined rapidly. In the system the spectrums of scintillation, spread and of spot dancing may be simultaneously measured in a sampling rate of 3,000/s. The measurement precisions predicted are of 0.5% to amplitude, of 3 micrometers to width and of 5 micrometers to spot dancing in the laboratory static air.
