HOLOGRAMS

The object is hit with laser light. The data is recorded onto a plate by capturing the reflected, diffracted and scattered light. The plate acts as a diffraction grating. When hit with a laser beam, it again diffracts light in the same angle. The image then appears pseudoscopic. Repeating the process will allow reconstruction of the original image. Continuous-wave laser holography

How Does a Projector Work? The projection system has an optical semiconductor known as the DLP chip with up to 2 million microscopic mirrors The mirrors are directed by the semiconductor, to reflect greyscale light To give color, the mirrors are modified to reflect back only certain colors of light

the white light generated by the lamp passes through a prism that divides it into red, green and blue. Each DLP chip is identified for each of these three colors the colored light that the micromirrors reflect is combined and passed through the projection lens to form an image. Basics of Projectors

Four main parts the electronics system, a laser light source, a combiner optic scanning mirrors.
