碩士 === 中華科技大學 === 機電光工程研究所碩士班 === 98 === Polarized light has many applications. As in this thesis, we studied the new applications of using the principle of the polarized light. First, a microscope of polarized light was made to monitor the potato Maltese cross and gelatinization since they change with temperature. Four experiments were compared for which could have the best results. Since the required experimental apparatuses are relatively simple, the method could be a good and simple way to view the Maltese cross. Second part of this research is the application of polarized light to view the color of transparent PE tablespoons made by injection molding in hot water. The best viewing angle can be determined by acting a force on a transparent PE disc to cause the disc colorful. The third part is the use of the polarized laser to take the holographic film. The brightness of photo images from different angles of shootings was compared.
