Lecture
This lecture covers the generation of elliptically polarized light by birefringent specimens, explaining the concepts of linear, circular, and elliptical polarization. It also delves into examples of retarders, contrast enhancement techniques in microscopy, and the principles behind Differential Interference Contrast (DIC) microscopy. The instructor discusses the formation of DIC images, the equipment and optics involved, and the interpretation of the DIC image through the manipulation of O-Ray and E-Ray pairs.
