Abstract
MEDIDOR OPTICO DE DESPLAZAMIENTOS ANGULARES MEDIANTE UNA COMPONENTE ROTATORIA DE LUZ. EL MEDIDOR OPTICO (1) COMPRENDE UNA FUENTE DE LUZ (4) INCORPORANDO CUATRO LEDS (5) ALIMENTADOS CON GENERADORES (61 A 64) DE IGUAL VOLTAJE PERO DESFASADOS UN CUADRANTE UNO DEL OTRO, Y CUATRO LAMINAS (7) POLARIZADORAS SUPERPUESTAS UNA A CADA LED, CUYOS PLANOS DE POLARIZACION ESTAN INCLINADOS 45 UNO DEL OTRO, EMITIENDO UNA COMPONENTE (9) ROTATORIA QUE ROTA CON VELOCIDAD ANGULAR (OE/2) MITAD QUE LA DE DICHO VOLTAJE, UN POLARIZADOR (11) Y UN REFLECTOR (12) AMBOS UNIDOS AL CUERPO (2) ROTATORIO CUYO DESPLAZAMIENTO SE DESEA MEDIR, Y UN FOTODETECTOR INCORPORADO EN EL DISPOSITIVO EMISOR (4'') DE LUZ. EL INSTRUMENTO (15) ELECTRONICO COMPARA LA SEÑAL (18) CORRESPONDIENTE AL HAZ LUMINOSO (13) REFLEJADO CON UNA SEÑAL (17) DE REFERENCIA DIRECTAMENTE EXTRAIDA DEL VOLTAJE DE ALIMENTACION.OPTICAL ANGLE DISPLACEMENT METER THROUGH A ROTATING LIGHT COMPONENT. THE OPTICAL METER (1) INCLUDES A LIGHT SOURCE (4) INCORPORATING FOUR LEDS (5) SUPPLIED WITH GENERATORS (61 TO 64) OF THE SAME VOLTAGE BUT OFFSET ONE QUADRANT ONE OF THE OTHER, AND FOUR SHEETS (7) POLARIZERS OVERLAPPED EACH EACH LED, WHOSE POLARIZATION PLANES ARE INCLINED 45 EACH OTHER, ISSUING A ROTARY COMPONENT (9) THAT ROTATES WITH ANGULAR SPEED (OE / 2) HALF THAT OF SUCH VOLTAGE, A POLARIZER (11) AND A REFLECTOR (12) BOTH UNITED TO THE ROTARY BODY (2) WHOSE DISPLACEMENT IS DESIRED TO MEASURE, AND A PHOTODETECTOR INCORPORATED IN THE LIGHT EMITTING DEVICE (4 ''). THE ELECTRONIC INSTRUMENT (15) COMPARES THE SIGNAL (18) CORRESPONDING TO THE LIGHT BEAM (13) REFLECTED WITH A REFERENCE SIGNAL (17) DIRECTLY REMOVED FROM THE SUPPLY VOLTAGE.
