TUTORIAL OPTICAL INTERFEROMETER Russian patent published in 2000 - IPC

FIELD: tutorial devices. SUBSTANCE: interferometer is used to show light interference and to measure wavelength of light. Each light beam is passed through same layer but at slightly different angles to shape two overlapping light beams which ensures small difference in lengths of their paths and provides for shaping set of contrast interference rings; diffuse scattering effect is used for splitting primary light beam; light-splitting system has planar movable diffuser and planar reflecting mirror placed in parallel with the former. EFFECT: provision for obtaining interference pattern using standard equipment. 3 dwg
