A system includes a feedback loop that includes a light engine to generate light, a light engine controller to control operation of the light engine, a scanning device to scan a light beam across a range of scan angles to an incoupler of a waveguide, a photo-sensor to measure an amount of light outcoupled through the incoupler of the waveguide at the range of incident angles. The light engine controller adjusts one or more of a pulse duration, a phase, or a pulse frequency of the scanned light, based on an incident angle of the scanned light and the measured amount of light.

Coupling narrowband projector source light into display waveguides

A fixture for aligning tiled displays is provided. The fixture includes a frame. The fixture further includes a vision system supported by the frame, the vision system configured to image at predefined display corner positions defined by given display dimensions. The fixture further includes an attachment mechanism configured to attach the frame to an array of tiled displays each having the given display dimensions, such that the vision system images positions of the array corresponding to respective corners of a tiled display in the array, and adjacent display corner positions.

Fixture for aligning tiled displays

A coincident fastener for use with a display unit of a configurable imaging system, comprising a screw for insertion through the display unit, wherein the screw includes a head portion, a threaded male portion at an end of the screw opposite the head portion, and an anti-rotation locking mechanism for locking the screw relative to the display unit.

Coincident fasteners for configurable imaging systems

For use in an imaging system having a plurality of adjacent display units, the improvement comprising a thermal actuator in at least one of the display units for moving a screen thereof away from a chassis thereof when the said display unit exceeds a predetermined temperature, so as to prevent mechanical interference between the adjacent display units.

Thermal actuator for configurable imaging systems

An expanding chassis for an imaging unit is provided, the expanding chassis for use in imaging systems having a plurality of imaging units arranged in an array. The expanding chassis comprises a rigid frame for housing a light engine and related circuitry, and for mounting a screen on a front surface of the rigid frame for use with the light engine. The expanding chassis further comprises at least one expandable interface pad on at least one side of the rigid frame. The rigid frame and the expandable interface pad have a combined thermal expansion characteristic that provides an overall expansion in the expanding chassis that substantially matches the expansion of the screen.
