MAGNETOOPTICAL VALVE Russian patent published in 2004 - IPC

FIELD: optics. SUBSTANCE: magnetooptical valve has polarizer, amplitude beam splitter containing N beam splitting mirrors placed consistently positioned in series on optical axis. Proper magnetooptical polarization rotator placed in longitudinal magnetic field of magnetic system with axial magnetization is located in path of each direct ray going out of beam splitter. Proper optical phase inverter is placed in path of each direct ray going out of N magnetooptical rotators of polarization plane. System of N mirrors and amplitude optical mixer with N inputs for direct rays and one output for direct ray hitting analyzer are arranged in series in path of optical phase inverters of direct rays. EFFECT: enhanced functional characteristics thanks to increased ray stability. 1 dwg
