1. A projection system, comprising:
- a laser light source;
an image generator to modulate laser light from the laser light source to form a projection image;
a projection lens assembly downstream of the image generator to project the projection image; and
a despeckling device operably positioned intermediate the laser light source and the image generator, the despeckling device being configured to limit laser speckle of the projected projection image.

Abstract
A projection system including at least a laser light source, an image generator, a projection lens assembly, and a despeckling device. The image image generator modulates laser light from the laser light source to form a projection image. The projection lens assembly is positioned downstream of the image generator and projects the projection image. The despeckling device limits laser speckle of the projected projection image.
