Abstract:
1. An optical parameter measuring apparatus to measure optical parameters of an object, comprising: a light source that radiates light onto the object; a polarizing module that converts the light from the light source into six polarizing lights prior to being incident onto the object; a Stokes polarimeter that receives the polarizing lights that have passed through the object and respectively generates light information according to the received polarizing lights passing through the object; and a calculating module that calculates optical parameters of a plurality of Mueller matrixes of the object in accordance with the light information respectively produced by the Stokes polarimeter, including a linear birefringence, a circular birefringence, a linear dichroism, a circular dichroism and a Stokes vector, wherein the optical parameters of Mueller matrixes of the linear birefringence include a slow axis orientation angle and a retardance, wherein the optical parameters of Mueller matrixes of the linear dichroism include an orientation axis angle and a dichroism, wherein the optical parameter of Mueller matrixes of the circular birefringence includes an optical rotation angle, and wherein the optical parameter of Mueller matrixes of the circular dichroism includes a value of circular amplitude anisotropy.
