FIELD: optics. SUBSTANCE: autocorrelator has light beam splitter, variable optical delay line, direct and delayed beam coincidence unit which are optically connected with recording unit. Light beam splitter, variable optical delay line and direct and delayed beam coincidence unit are made in form of plane-parallel double refraction plate mounted for rotation about its axis perpendicular to main plane of plate. EFFECT: simplification of construction and enhanced adjustment of autocorrelator. 1 dwg
