課程概述 |
This course describes the nature of holographic and lithographically formed diffraction volume/thin gratings and necessary tools for their design and analysis. Course topics include a description of the interference and Fourier relations that determine the amplitude of diffracted fields, analysis of volume gratings, and properties of holographic recording materials, binary gratings, and analysis of applications of holography including bio-imaging and data storage, fiber Bragg gratings, and polarization control elements.
This class can complement the courses of Optics (光學導論) and Advanced Bio-Optical Microscopy (高等生物光學顯微術).
