Cgh optics
WebOptiScan Simulation Program. The OPTISCAN program is a tool for simulating the operation of optical systems. What differentiates OPTISCAN from other simulation software is the wide range of wave-optics phenomena that are available and the easy-to-use graphical user interface (GUI). OPTISCAN can be used as a simple demonstrator of … WebConventional interferometry can provide useful information about a cylindrical optic's surface, but a Computer Generated Hologram (CGH) can be used to gather a complete description of the surface. A CGH can …
