FIELD: optics. SUBSTANCE: beam of monochromatic light emitted by source 1 falls in beam splitter 2 where it is divided into two beams. Beam reflected from beam splitter 2 falls on immobile flat reflector 4, is reflected from it and passing through beam splitter 2 hits radiation receiver 5. Second beam from source 1 passed through beam splitter 2 falls on mobile reflector 3 at acute angle, is reflected backwards and reflected from beam splitter 2 hits radiation receiver 5. Interference picture is observed in receiver 5. EFFECT: simplified design, improved functional stability. 2 cl, 4 dwg
