초록
In this paper, some optical parameters which have effects on the measuring precision and sensitivity of optical current sensor are analyzed. Each parameter occurs changes of specific characteristics of optical sensor system. The influences of performance and characteristics variation of optical current sensor are described in accordance with the changes of optical output power, optical bias point which is called phase difference, and a specific constant related to sensor material and wavelength of light source.
