Abstract
A system and method for calibration of a display system with a linear modulator array that includes: a light source; a linear array of light modulating devices driven by a controller; a projection lens system that creates a line image of the linear array on a screen; a scanning mirror that sweeps the line image across the screen to form a two-dimensional scene; and an image sensor containing an area array of light sensitive detectors that captures image intensity data from the two-dimensional scene and transmits the image intensity data to the controller, wherein the controller converts the image intensity data into a one-dimensional array of correction factors for the linear array of light modulating devices.
