Abstract
INTERFEROMETRO CON RED DE DIFRACCION PARA LA MEDIDA DE LONGITUDES. COMPRENDE UN PRISMA (12) CON UNA SOLA RED (18) DE DIFRACCION ACOPLADA EN SU CARA ANTERIOR ACTUANDO COMO DIVISOR DEL HAZ (15) EMITIDO POR UN DIODO (13) LASER, QUE TIENE AL MENOS UNA CARA (F) LATERAL INCLINADA DONDE SE REFLEJA TOTALMENTE UNO DE LOS ORDENES DIFRACTADOS EL CUAL VUELVE A SER DIFRACTADO EN DIRECCION OPUESTA O A SER REFLEJADO, UN RETROREFLECTOR (29) MOVIL Y EL RECEPTOR ELECTRONICO. DEBIDO A LA CONFIGURACION DE LA RED (12) Y A LA CONSTRUCCION DEL PRISMA, LA SUPERPOSICION INTERFERENCIAL DE LOS HACES DE REFERENCIA (17'') Y DE MEDIDA (17) NO DEPENDE DE LA TOLERANCIA DE LA POSICION ANGULAR DEL PRISMA RESPECTO DEL EJE DEL HAZ (15) EMITIDO, SIMPLIFICANDOSE SU AJUSTE OPTICO.INTERFEROMETER WITH DIFFERATION NETWORK FOR MEASURING LENGTHS. UNDERSTAND A PRISM (12) WITH A SINGLE DIFFERATION NETWORK (18) COUPLED IN ITS PREVIOUS SIDE ACTING AS A DIVIDER OF THE BEAM (15) ISSUED BY A LASER DIODE (13), WHICH HAS AT LEAST ONE SIDE FACE (F) INCLINED WHERE IT IS FULLY REFLECTS ONE OF THE DIFFACTED ORDERS WHICH IS DIFFACTED AGAIN IN THE OPPOSITE DIRECTION OR IS REFLECTED, A MOBILE RETROREFLECTOR (29) AND THE ELECTRONIC RECEIVER. DUE TO THE CONFIGURATION OF THE NETWORK (12) AND THE CONSTRUCTION OF THE PRISM, THE INTERFERENTIAL OVERLAP OF THE REFERENCE (17 '') AND MEASUREMENT BEAMS (17) DOES NOT DEPEND ON THE TOLERANCE OF THE ANGULAR POSITION OF THE PRISM AXIS OF THE MAKE (15) ISSUED, SIMPLIFYING YOUR OPTICAL ADJUSTMENT.
