IR fiber system for remote spectroscopy and noncontact control of IR radiation

A simple sensor used for remote detection of middle infrared radiation is presented. It is based on the use of cooled semiconductor detectors as a sensitive unit and middle infrared fibers for radiation transfer from investigated object to the detector. Sensors of this kind are promising for detection of radiation emitted by weakly heated objects, for measurements of their temperature and temperature gradients. The unit could be used in medical diagnostics, remote spectroscopy measurements, and chemical control.
