Abstract
In this work, a multilayered dielectric film and metallic film are used as reflecting surface to fabricate light pipe. Linearly polarized laser beam with wave length of 532nm enters into the light pipe. After multi-reflection process, laser beam come out from the light pipe. We have found that the polarization state of linearly polarized incident light after reflection are different for the light pipe coated with metal and multilayered dielectric film. We also found a distributed polarization characteristic in the output optical field. The polarization degree has been simulated by using ZEMAX software. Laser speckle contrast from a glass diffuser is measured to exam the simulated result.
