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.
