Abstract

UN TRANSMISOR DE LUZ LASERICA QUE INCLUYE UN DIODO EMISOR DE LUZ LASERICA (1, 2,) COLOCADO EN UN PUNTO FOCAL DE UNA LENTE CON FORMA ESPECIAL (3, 4) QUE PRODUCE UN HAZ CON FORMA DE ABANICO INTENSO, MUY FINO. UN DETECTOR DE PROXIMIDAD UTILIZA UNO O DOS DE TALES TRANSMISORES DE LUZ LASERICA (INFRARROJA) PARA RADIAR UN HAZ CON FORMA DE ABANICO QUE ES INTERCEPTADO POR UNA PERSONA U OBJETO CON LO QUE SE DISPERSA LA LUZ LASERICA, MEDIANTE UNA REFLEXION DIFUSA. UNA LENTE CILINDRICA (5) RECIBE UN COMPONENTE REFLEJADO Y ESTE ES DETECTADO POR UNOS SENSORES (6) QUE SE ENCUENTRAN CONECTADOS A UN CIRCUITO QUE INCLUYE UN DETECTOR SINCRONICO (12) Y UNA RED COMPARADORA (13, 14). EL DETECTOR SINCRONICO (12) ES ACCIONADO POR UN OSCILADOR DE ONDAS CUADRADAS (8) QUE MODULA LA LUZ LASERICA.
