摘要：FIELD: single-photon interference. ^ SUBSTANCE: method can be used in fundamental research of quantum-mechanical interaction nature. Beam of continuously operating coherent electromagnet radiation is split to two flows which both are subject to convergence onto screen to form interference pattern. The flow is overlapped periodically at two points at least. Changes in interference pattern are registered by means of photo detectors. Boundary conditions, which correspond to transient from availability and absence of interference pattern, are determined by changing frequency of overlapping and length of part to be overlapped. Speed to be found is judged from relation of distance passed by overlapped flow between parts of overlapping to preset duration of open state in period. ^ EFFECT: improved precision; high fidelity. ^ 2 dwg
