I’ve had a talk about “Holography” today. It was a project for my optics class. So I thought It would be a good idea to write a little about this matter.
Holography is a Greek word meaning “whole-drawing”. This method records the light field instead of only recording a reflection of the object. There are different types of holograms like transmission holograms, reflection holograms, rainbow holograms (which we frequently see used for security on credit cards and passports and etc.)
