    摘要: A projector and a system comprising a projector and a handheld device are described. In a preferred embodiment, a projector for projecting an image includes a back section and a front section. The back section has a bottom surface for resting on a supporting surface, and the front section has an optical window for projecting light indicative of the image. The front section is tilted with respect to the bottom surface of the back section to define a tilt angle. The system includes a video-output generating handheld device, and a display device controlled by control signals generated by the handheld device. The handheld device and the display device are interconnected with no more than one physical video signal connection.

    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.
