Abstract:
An arrangement for displaying an image for viewing by a human eye, comprising:a) a housing having a movable screen which has a front surface and a rear surface, and an optically diffusive property; b) an energizable laser supported by the housing for projecting a laser beam toward the rear surface of the screen when energized and upon moving the screen to a deployed position; c) a scanner supported by the housing for sweeping the laser beam along a plurality of light paths over the rear surface of the screen for diffusion therethrough; and d) a controller supported by the housing and operatively connected to, and operative for energizing, the laser at selected positions of the laser beam in at least one of the light paths to generate individual light pixels at the selected positions, and at a refresh rate at which the pixels persist to enable the eye to steadily view the image comprised of a light pattern of the pixels visible on the front surface of the screen.
