【Abstract】 With twin receiving optical fiber method, a fiber-optic angle sensing principle which can compensate the change of intensity automatically is introduced . Theoretically , the compensation mechanism of sensing device is analyzed and the characteristic modulating function were given. The experimental results shown that this modulating device can effectively compensate the effect of light source variation due to electric source unstableness or aging of the light source device on the measuring result.更多还原
