Abstract

SENSOR DE PROXIMIDADE FOTÔNICA. Um sensor fotônico de proximidade e sistema de sensores fotônicos são fornecidos. O sensor fotônico de proximidade inclui uma primeira fonte de luz, uma segunda fonte de luz, e um dispositivo magnético-ótico. O dispositivo magnético-ótico recebe a luz emitida proveniente das primeira e segunda fontes de luz, e é responsivo às variações de um campo magnético para girar a luz proveniente de uma das fontes significativamente mais do que a luz proveniente da outra fonte de luz.
