Abstract

PARA CONTROLAR LA CONEXION DE UNA ESTRUCTURA EN NIDO DE ABEJAS (2) SOBRE UN SOPORTE (4) SE INTRODUCE EN UN ALBILLA DEL NIDO, UNA FIBRA OPTICA (10), DICHA FIBRA DE ILUMINACION, CONECTADA A MEDIOS 16 DE EMISION DE LUZ, ASI COMO EN AL MENOS UN ALVEOLO ADYACENTE A LA PRECEDENTE, UNA FIBRA DE MEDICION (12-1, 12-2) CONECTADA A MEDIOS (18-1, 18-2) DE CONVERSION DE LA LUZ EN UNA SEÑAL ELECTRICA. UN HAZ DE ILUMINACION SE EMITE EN EL ALBILLA DE LA FIBRA DE ILUMINACION Y SE DETECTA, DE MANERA SINCRONA, LA LUZ INDUCIDA POR EL HAZ DE ILUMINACION EN EL O LOS ALVEOLOS ADYACENTES QUE CONTIENEN UNA FIBRA DE MEDICION.
