Integrated light concentrator

   
   

An infrared sensor including an absorber for absorbing incident infrared power to produce a signal representing the temperature of a target object, a frame supporting a membrane which carries the absorber, the frame including a plurality of reflecting surfaces disposed about the circumference of an opening over which the membrane spans for reflecting incident infrared power toward the absorber. By concentrating incident infrared power through reflection, the temperature difference between the absorber and the surrounding frame is increased, thereby producing an increased electrical output from the sensor.

Um sensor infravermelho including um absorvente para que o poder infravermelho do incident absorvente produza um sinal que representa a temperatura de um objeto do alvo, um frame que suporta uma membrana que carregasse o absorvente, o frame including um plurality de superfícies refletindo dispôs sobre a circunferência de um excesso da abertura que a membrana medisse para o poder infravermelho refletindo do incident para o absorvente. Concentrando o poder infravermelho do incident com a reflexão, a diferença da temperatura entre o absorvente e o frame circunvizinho é aumentada, desse modo produzindo uma saída elétrica aumentada do sensor.
