Fiber optic method for measuring the intensity of IR radiation

A high sensitivity fiber-optic method for registration of infrared (IR) radiation is proposed. The method is based on the effect of modal interference in an optical fiber. The speckle pattern is registered in the far field of a multimode fiber and is processed by a PC for deriving the output signal....

Zusammenfassung:A high sensitivity fiber-optic method for registration of infrared (IR) radiation is proposed. The method is based on the effect of modal interference in an optical fiber. The speckle pattern is registered in the far field of a multimode fiber and is processed by a PC for deriving the output signal. The method also can be applied for registration of temperature, mechanical vibrations, etc.
