Abstract: An image projection system includes an illumination source, a linear polarizer, and an eyepiece waveguide including a plurality of diffractive in-coupling optical elements. The eyepiece waveguide includes a region operable to transmit illumination light from the illumination source. The image projection system also includes a polarizing beamsplitter, a reflective structure, a quarter waveplate disposed between the polarizing beamsplitter and the reflective structure, and a reflective spatial light modulator.

Abstract: An image projection system includes an illumination source and an eyepiece waveguide including a plurality of diffractive incoupling optical elements. The eyepiece waveguide includes a region operable to transmit light from the illumination source. The image projection system also includes a first optical element including a reflective polarizer, a second optical element including a partial reflector, a first quarter waveplate disposed between the first optical element and the second optical element, a reflective spatial light modulator, and a second quarter waveplate disposed between the second optical element and the reflective spatial light modulator.

Abstract: A laser system comprising a laser assembly for generating a light beam, and collimation assembly movable axially with respect to the laser assembly and being positioned in the optical path of the light beam. The collimation assembly comprises a collimation lens group comprising a first lens component positioned within a first lens mounting cell, a second lens component positioned within a second lens mounting cell and provided with a central portion for receiving and cooperating with the first cell to thereby adjust the axial spacing between the first and second lens components, means for radially adjusting the position of the second cell with respect to the first cell to thereby radially adjust the optical axis of the second lens component with respect to the optical axis of the first lens component, and means formed in the central and flange portions of the second cell for creating flexure therein.
