Abstract
METODO PARA DETERMINAR LA CALIDAD OPTICA DE UNA PLACA TRANSPARENTE, DE CRISTAL LAMINADO, EN EL QUE DOS HACES LUMINOSOS PARALELOS SON DIRIGIDOS SOBRE LA PLACA FORMANDO UN ANGULO AGUDO RESPECTO A LA NORMAL DE LA MISMA; LOS HACES REFLEJADOS POR LA PLACA SON RECIBIDOS SEPARADAMENTE CON AYUDA DE UN DETECTOR FOTOSENSIBLE, Y SE EVALUA LA DIRECCION DE LOS HACES LUMINOSOS REFLEJADOS. LOS CUATRO HACES LUMINOSOS A1, A2, B1 Y B2 REFLEJADOS POR LAS DOS SUPERFICIES DE LA PLACA SON TODOS RECIBIDOS POR UN DETECTOR SENSIBLE A LA POSICION, EL ESPACIAMIENTO EXISTENTE ENTRE LOS HACES REFLEJADOS A Y B Y EL ANGULO DE INCIDENCIA DE LOS MISMOS SON AJUSTADOS COMO FUNCION DEL GROSOR DE LA PLACA DE MODO QUE LOS HACES LUMINOSOS REFLEJADOS AL, A2, B1 Y B2 SEAN DETECTADOS DE MANERA ESPACIALMENTE SEPARADA, Y, A PARTIR DE LOS PUNTOS DE IMPACTO DE LOS CUATRO HACES REFLEJADOS SOBRE EL DETECTOR SENSIBLE A LA POSICION SE CALCULAN PARAMETROS PARA LA DETERMINACION CUANTITATIVA DE LA CALIDAD OPTICADE LA PLACA.
