Abstract

DISPOSITIVO REPRODUCTOR TERMICO (10) TIENE UNA SOLA PLACA DE CIRCUITO INTEGRADO (86) QUE REALIZA DIFERENTES FUNCIONES DE PROCESAMIENTO (ASP) DE SEÑALES ANALOGICAS. EL DISPOSITIVO REPRODUCTOR (10) TIENE UNA MATRIZ DETECTORA (50) COMPUESTA DE UNA PLURALIDAD DE DETECTORES (50'') CADA UNO DE LOS CUALES GENERA UNA SEÑAL ELECTRICA (78) INDICATIVA DEL FLUJO LUMINOSO DE INFRARROJO INCIDENTE EN LA MISMA. ESTAS SEÑALES ELECTRICAS (78) SE PROCESAN Y SE PROPORCIONAN EN LA FORMA DE SEÑALES DE VIDEO ANALOGICAS EN SERIE (52) A LA PLACA ASP (86). LA PLACA ASP (86) INCLUYE CIRCUITERIA (200) PARA RECTIFICAR LA RESPONSIVIDAD DIFERENCIAL DE LAS MATRICES DETECTORAS FABRICADAS EN SERIE (50), CIRCUITERIA (202) PARA RECTIFICAR LA GANANCIA DE LA SEÑAL ANALOGICA EN SERIE (52), Y CIRCUITERIA (206) PARA MEDIR LA GANANCIA DE UNA SEÑAL ANALOGICA EN SERIE DE PROCESAMIENTO (90) QUE LA PLACA ASP (86) PROPORCIONA A UN CONVERTIDOR (92) ANALOGICO A DIGITAL (AID) DEL DISPOSITIVO REPRODUCTOR TERMICO (10). LA PLACA ASP (86) ANTERIOR INCLUYE UN ALMACENAMIENTO (204) PARA MANEJAR EL CONVERTIDOR A/D (92), Y UN GENERADOR DE REFERENCIA DE TENSION Y CORRIENTE (212) PARA PROPORCIONAR DE ESA MANERA AMBAS REFERENCIAS (213) INTERNAMENTE AL ADC IC (86) BIEN EXTERNAMENTE DE ESTE IC A OTROS COMPONENTES DEL DISPOSITIVO REPRODUCTOR (10) INCLUYE EL DETECTOR (50) Y EL CONVERTIDOR A/D(92). UN MICROCONTROLADOR (122) DEL DISPOSITIVO REPRODUCTOR TERMICO (10) PROMEDIA LA GANACIA DE LA SEÑAL DE SALIDA (90) PROPORCIONADO POR EL CONVERTIDOR A/D (92) Y USA ESTA INFORMACION PARA CALCULAR LA RESPONSIVIDAD Y SEÑALES DE CONTROL DE GANANCIA (210,209) APLICADA A LA SEÑAL DE VIDEO ANALOGICA EN SERIE (5) PROPORCIONADA A LA PLACA ASP (86), DE MANERA QUE EL CONVERTIDOR A/D (96) PROPORCIONA UNA SEÑAL DE VIDEO ANALOGICA (90) A NIVEL DE MEDIA ESCALA PARA LA SEÑAL DE ENTRADA A ESTE CONVERTIDOR A/D (92).
