1. A system for reducing speckle in an image produced from a light source, comprising:
- a light source operable to transmit an input beam of light;
a line generating element in optical communication with the input beam of light, the line generating element having a collection of optical elements configured to convert the input beam of light into one or more individual line beams of light;
a vibration source coupled to the line generating element, the vibration source configured to vibrate the line generating element back and forth in a direction substantially transverse to an axis of the collection of optical elements;
a spatial light modulator positioned in optical communication with the line generating element, the spatial light modulator configured to modulate the one or more individual line beams of light; and
a display screen positioned to receive the modulated individual line beams of light.

Abstract
Provided is a method and system for reducing speckle in an image produced from a light source. The method, in one embodiment, includes providing a line generating element, the line generating element having a collection of optical elements having an axis. The method, in this embodiment, further includes directing an input beam of light at the line generating element while the line generating element is being vibrated back and forth in a direction substantially transverse to the axis.
