Abstract

PARA ESCRIBIR BITS ( PIXELS) SOBRE UN BLANCO (36) MEDIANTE EXPLORACION DE UN HAZ (13) LASER DE ONDA CONTINUA, A TRAVES DE UN CONJUNTO O ARRAY DE ESPEJOS CONCAVOS (M1 ON REFLEJADA DESDE EL DISPOSITIVO (M1 REFLEJA EN LOS ESPEJOS UNA FILA DE PUNTOS FIJOS (D1 RE EL BLANCO (36) DURANTE CADA EXPLORACION. PARA ESCRIBIR UN PATRON MATRIZ DE PUNTOS, DESPUES DE ESCRIBIR CADA FILA DE PUNTOS SOBRE EL BLANCO (36), EL BLANCO (36) SE TRASLADA PERPENDICULARMENTE A LA FILA DE PUNTOS (D1 POR UN RODILLO (37), Y OTRA FILA DE PUNTOS SE ESCRIBE A CONTINUACION SOBRE EL BLANCO (36). EL HAZ LASER (13) PUEDE MODULARSE MIENTRAS SE EXPLORA A TRAVES DEL CONJUNTO DE ESPEJOS CONCAVOS (M1 DEL CONJUNTO DE ESPEJOS CONCAVOS (M1 UN ESPEJO ROTATORIO, QUE PUEDE SER PLANO O POLIGONAL (34), CON MULTIPLES FACETAS. EN UNA VERSION PREFERENTE (FIGURA 9), SE ESCRIBEN SOBRE EL BLANCO LINEAS DE LONGITUD Y ANCHURA VARIABLES (EN VEZ DE PUNTOS). ESTO SE LLEVA A CABO EXPLORANDO EL HAZ LASER DE ONDA CONTINUA A TRAVES DE UN SISTEMA DE LENTES VARIABLES (106, 108). LA EXPLORACION SE HACE REFLEJANDO EL HAZ DESDE UN ESPEJO ROTATORIO (104), CON LO QUE EL PASE RAPIDO O BARRIDO A TRAVES DEL SISTEMA DE LENTES SE PROYECTA COMO UNA LINEA SOBRE EL BLANCO.
