Abstract
Official abstract text for this publication.
An optical parameter measuring apparatus for measuring optical parameters of an object includes a light source, a polarizing module, a Stokes polarimeter and a calculating module. The light source emits a light which is polarized by the polarizing module and received by the Stokes polarimeter. According to the light information generated by the Stokes polarimeter, Mueller matrixes of linear birefringence, circular birefringence, linear dichroism, circular dichroism and linear/circular depolarization of the object, and Stokes vector established according to the Mueller matrixes, the calculating module calculates the optical parameters.
First claim
Opening claim text (preview).
We claim: 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 pas…
