Abstract:
1. An image projecting device comprising: a spatial light modulating (SLM) pixel arrangement having a pixel pitch substantially not exceeding 50 μm and defining an active surface; first and second lens arrays respectively located at opposite surfaces of said SLM pixel arrangement and being integral with said SLM pixel arrangement forming together with said SLM pixel arrangement a common SLM unit, such that each lens in the first array and a respective opposite lens in the second array are associated with a corresponding one of the pixels, each of said first and second lens arrays being implemented in a polymer spacer and each being either spaced from the respective surface of the opposite surfaces of the pixel arrangement a predetermined distance or being in physical contact with said respective surface; a light source system (LSS) operable to produce an incident light beam of a predetermined cross section corresponding to the size of said active surface; and a magnification optics accommodated at the output side of the SLM pixel arrangement.
