Abstract

DISPOSITIVO PARA LA EVALUACION DE BRILLO NO ESPECULAR. PERMITE NOVEDOSAMENTE OBTENER VALORES DE BRILLO CORRESPONDIENTES CON LOS REALES EN LA EVALUACION DE SUPERFICIES (S) CON RELIEVES, O RUGOSAS, CUYOS REFLEJOS ESTAN FORMADOS MAYORITARIAMENTE POR COMPONENTES NO ESPECULARES. CONSISTE EN DISPONER VARIOS ILUMINANTES (1, 2, ... N) CON DISTINTOS ANGULOS DE INCIDENCIA (A1, A2, ... AN) RESPECTO DE LA SUPERFICIE A MEDIR (S), RECOGIENDOSE LOS DISTINTOS REFLEJOS MEDIANTE UN RECEPTOR CONVENCIONAL (R) QUE TRADUCE DICHOS REFLEJOS A VALORES DE BRILLO.DEVICE FOR EVALUATION OF NON-SPECULAR BRIGHTNESS. IT NEWLY ALLOWS TO OBTAIN BRIGHTNESS VALUES CORRESPONDING WITH THE REAL IN THE EVALUATION OF SURFACES (S) WITH RELIEF, OR ROUGH, WHICH REFLECTIONS ARE FORMED BY MAJORITY NON-SPECIFIC COMPONENTS. IT CONSISTS OF ARRANGING VARIOUS ILLUMINANTS (1, 2, ... N) WITH DIFFERENT ANGLE OF INCIDENCE (A1, A2, ... AN) WITH RESPECT TO THE SURFACE TO BE MEASURED (S), COLLECTING THE DIFFERENT REFLECTIONS BY MEANS OF A CONVENTIONAL RECEIVER (R ) THAT TRANSLATES THESE REFLECTIONS TO BRIGHTNESS VALUES.
