Abstract: A system for projecting 2D images, providing a computerized representation of a first, dense, grid of spatial 3D coordinates which respectively correspond to a set of time-points evenly distributed along a time-dimension with constant time-discretization; deriving a dense 2D representation of an image, whose coordinate pairs respectively correspond to said set of time-points; d. Defining a sparse 2D grid of second coordinate pairs, spaced such that distances between any two adjacent coordinate pairs along a row of said sparse 2D grid are constant; and finding, coordinate pairs closest to the second sparser grid to yield a third grid, and a laser controller to control the laser to project a digitally represented image, from said distance, timed to project pixels whose locations respectively correspond to the subset of uniformly distanced positions forming said third grid, thereby to prevent image distortion despite non-uniformity of micro-mirror's angular velocity.

Abstract: A system and method for providing a dimming factor of N using a laser display device having plural colored laser diodes each generating a colored laser beam according to control parameters. At least one of the control parameters of at least one of the laser diodes is varied, at least one of the control parameters being operative to reduce intensity of at least one of the colored laser beams. Varying may comprise providing a dimming factor of m
