Abstract: A wedge mechanism for light modulator image adjustment is provided. In particular, a device is provided comprising: a first plate; a second plate for receiving a light modulator; one or more biasing mechanisms to bias the second plate in a biased position relative to the first plate, to allow the second plate to move with respect to the first plate; first and second wedge devices configured respectively interact with a first and second edges of the second plate to move the second plate, relative to the first plate, against the one or more biasing mechanisms, the second edge of the second plate being about perpendicular to the first edge of the second plate; and first and second wedge device adjustment mechanisms configured to respectively adjust positions of the first and second wedges device relative to the first and second edges, to move the second plate.

Abstract: A light engine for use in a projector, comprising a motorized adjustable convergence mechanism for fine adjusting the relative positions of red, green and blue channel sub-assemblies. Motors are mounted on fixed elements of the sub-assemblies for driving movable elements thereof, including imaging devices thereof such as digital micromirror devices.

Abstract: A light engine for use in a projector, comprising an adjustable convergence mechanism for fine adjusting the relative positions of red, green and blue channel sub-assemblies. In one embodiment, motors are mounted on fixed elements of the sub-assemblies for driving movable elements thereof, including imaging devices thereof such as digital micromirror devices. In another embodiment, manual adjustment screws are provided in place of the motors, and wedge locking mechanisms are provided for driving and locking the position of the movable elements imaging devices mounted thereon.
