Abstract:
Projection systems and/or methods comprising a blurring element are disclosed In one embodiment, a blurring element may comprise a first plate having a pattern on a first surface and second plate. The first plate and the second plate may comprise material having a slight difference in their respective index of refraction. In another embodiment, a blurring element may comprise a first plate having a pattern thereon and a second immersing material. The blurring element may be placed in between two modulators in a dual or multi-modulator projector system. The blurring element may be configured to give a desired shape to the light transmitted from a first modulator to a second modulator.

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.
