ABSTRACT:
A light detector is disclosed for measuring the temperature of an object. The light detector includes a lens assembly for accepting light emitted from the object, an aperture, and a mirror for reflecting the infrared energy of the object into a fiber optic cable. The fiber optic cable is connected to a depolarizing element to which pressure is externally applied. The depolarization element relays the infrared energy into a detection portion and a signal processing portion for calculating temperature. Before the infrared light enters the fiber optic cable, a chopper, controlled by a driving circuit, chops the infrared energy reflected by the mirror.
