Generating luminance uniformity in a rear projection display system is provided. The method comprises calculating luminance generated by a projector on a rear projection screen relative to a design eye position in front of the screen. A baseline luminance is determined for each primary color according to the luminance. Luminance of all locations on the screen is corrected toward the baseline. Correction is allocated between an optical filter and electronic correction. Luminance is measured at calibration points on the screen. The electronic correction for a color image is adjusted according to the allocation and the luminance at the calibration points to produce a corrected color image for projection from the projector. The corrected color image is projected from the projector and through the optical filter. The optical filter is configured to dim specified areas within the corrected color image according to the allocation.

Simulation display system, spatial image luminance uniformity

A method for setting an output of a projector of a display system, is provided. The method includes displaying an image on a projector screen using the projector, measuring a light characteristic emanating from the projector screen using a first meter on a first side of the projector screen, adjusting the output of the projector until a desired value of the light characteristic is measured at the first meter, measuring the light characteristic of light emitted from the projector, with a second meter on a second side of the projector screen, to obtain a light characteristic measurement that corresponds to the desired value, and storing the light characteristic measurement that corresponds to the desired value.

Systems and methods for calibrating and aligning displays

A system for tracking a gaze of an operator includes a head-mounted eye tracking assembly, a head-mounted head tracking assembly and a processing element. The head-mounted eye tracking assembly comprises a visor having an arcuate shape including a concave surface and an opposed convex surface. The visor is capable of being disposed such that at least a portion of the visor is located outside a field of view of the operator. The head-mounted head tracking sensor is capable of repeatedly determining a position of the head to thereby track movement of the head. In this regard, each position of the head is associated with a position of the at least one eye. Thus, the processing element can repeatedly determine the gaze of the operator, based upon each position of the head and the associated position of the eyes, thereby tracking the gaze of the operator.
