Abstract
A light analyzer with a first light source configured and disposed for irradiating with a first light an object disposed at an object location. A second light source is configured and disposed for irradiating the object with a second light that is preferably polarized along a first axis. A light receiving element is configured and disposed for receiving the first and second light reflected from the object and comprising a sensing device that is configured for sensing and producing an image corresponding to the reflected light. The light receiving element preferably comprises a polarizing filter configured for polarizing the reflected second light along a second axis at an angle to the first axis for reducing glare and reflection.
