Projection systems with despeckled laser light

摘要

An apparatus and method for the projection of stereoscopic images that includes a pulsed laser that generates green light and an optical fiber that generates stimulated Raman scattered light. The stimulated Raman scattering light is divided into green light and red light and the colors are used to form stereoscopic images. Additional lasers may be added to meet specific primary color targets and to balance the brightness of the images for each eye.

主权项

1. An optical apparatus comprising:
a pulsed laser that generates a first green light; and an optical fiber; wherein the first green light is focused into the optical fiber; the optical fiber generates a stimulated Raman scattering light that enhances an aspect of a light output of the optical fiber and broadens a spectrum of the first green light to produce a first red light; the light output from the optical fiber is separated into a second green light and the first red light; the second green light is used to form a green primary of a stereoscopic image; and the first red light is used to form a first red primary of the stereoscopic image.
