    摘要： The present invention provides a projection display comprising an illumination system comprising at least one laser source unit and configured and operable for producing one or more light beams; a spatial light modulating (SLM) system accommodated at output of the illumination system and comprising one or more SLM units for modulating light incident thereon in accordance with image data; and a light projection optics for imaging modulated light onto a projection surface. The illumination system comprises at least one beam shaping unit comprising a Dual Micro-lens Array (DMLA) arrangement formed by front and rear micro-lens arrays (MLA) located in front and rear parallel planes spaced-apart along an optical path of light propagating towards the SLM unit, the DMLA arrangement being configured such that each lenslet of the DMLA directs light incident thereon onto the entire active surface of the SLM unit, each lenslet having a geometrical aspect ratio corresponding to an aspect ratio of said active surface of the SLM unit.

    摘要： An image projection system is presented. The system comprises an optical unit and a connectable thereto control unit. The optical unit is configured to define an illumination channel for illuminating an object, an imaging channel for creating an image of the object from light collected therefrom and generating image data indicative thereof, and a projection channel for projecting an image of the object on a projection target. The control unit is configured and operable for receiving and analyzing the image data, and for controlling the image creation and projection.
