Compensating techniques for he intensity in sensing and measuring with intensity type fiber optic sensor

摘要

In this paper, many compensatding techniques for the intensity in sensing and measuring with intensity type fiber optic sensor are summarized which have been developed in our lab. Fundamental principles, system structure, functions and charactertics of the compensating techniques for double-light-path and single-light-path are described in detail. The difference and relations between the two compensating techniques are also analyzed.
