摘要：
An immersion-type potassium titanyl phosphate (KTP) optical angle sensor (OAS) was proposed for angular displacement measurement in a homodyne interferometer. The KTP plate was attached on a precise rotational stage and then immersed in a glass square cell filled with liquid. A reliability comparison of the immersion glycerin and grapeseed oil was studied under different angle ranges and environmental conditions. Compared with glycerin, grapeseed oil was found to have better stability in providing enough reliability for practical usage in a general environment. At a dynamic angle range of 10 degrees, the best linearity of 0.9998 and a resolution of 2.12 x 10(-4)degrees was achievable.
