NEW PHOTODETECTOR - METER OF THE CORRELATION FUNCTION OF OPTICAL SIGNALS

摘要

The principles of device for measurements of correlation function counter optical signals are presented. Matrix photodetector is a basis new correlator. Each cell of matrix is photodetector sensitivity to an interference field. The examples of experimental implementation new photodetector presented. The interferograms for response of a photoresistor PbS and multialkaly vacuum phototube on an interference field of counter luminous fluxes from a source of coherent radiation by power 1 mw, λ= 633 nm are measured. The ratio signal noise for interference responsive was achieved more than one hundred.
