Abstract

PURPOSE:To make possible measurement of dancing and spreading of beams in real time by reducing the incoming beams, detecting and storing the same and performing statistical processing. CONSTITUTION:Incoming beams 3 having propagated in the atmosphere are reduced with receiving telecspoes 1, 2 and the reduced beams are scanned thereover with a knife edge 4, then from a detector 8 the corresponding output waveforms are obtained and are introduced into a sample gate 9, where the sample numbers and sample intervals of the data are set and the output waveforms thereof are stored 10. At this time, the psoition information of the beams are applied from the chopper 5 of the knife edge 4 to the device 10. The data having been stored in the device 10 are subjected to statistical processing in a CPU 11, whereby the dancing and spreading of the beams are measured in real time.
