Abstract

A method for remote current sensing which uses the reflective and transmission properties of metals for infrared and ultraviolet radiation incident on thin films of metals or compound crystals is discussed. The apparatus consists of an ultraviolet or infrared generator/transmitter, whichever is suitable. A radiation receiver is used to sense the reflected and transmitted radiation, which is then amplified and detected by suitable circuitry. Variation in percentage reflectivity or transmission is thus sensed as a function of the current changes in the core sensor. The reflectivity and cutoff wavelengths vary from metal to metal, depending on the frequency of the incident radiation
