Abstract

APARATO Y METODO PARA CALENTAR DISPOSITIVOS OPTICAMENTE TRANSMISORES O REFLECTORES SEGUN UN MODELO TERMICO PREDETERMINADO, EN DONDE SE EFECTUA UN CALENTAMIENTO ELECTRICO UNIFORME DE UNA VENTANILLA CIRCULAR (18) DE GERMANIO MONOCRISTALINO UTILIZANDO SU RESISTENCIA VOLUMETRICA Y PARES DE ELECTRODOS (20) ESPACIADOS POR IGUAL ALREDEDOR DE LA PERIFERIA DE LA VENTANILLA, SIENDO CONMUTADOS EN SECUENCIA DICHOS PARES DE ELECTRODOS A UN REGIMEN LO SUFICIENTEMENTE ALTO COMO PARA EVITAR TRANSITORIOS DE CONMUTACION TERMICA. EL INVENTO ES ESPECIALMENTE UTIL PARA CALENTAR LA VENTANILLA DE UNA TORRETA DE OBSERVACION MONTADA EN UN AVION.
