ABSTRACT:
An image projecting device is presented. The device comprises an SLM pixel arrangement; and two lens arrays. The lens arrays are respectively located at opposite surfaces of the SLM pixel arrangement and are integral with the SLM pixel arrangement, forming together with the SLM pixel arrangement a common SLM unit. Each lens in one array and a respective opposite lens in the other array are associated with a corresponding one of the pixels. Each of the lens arrays is implemented in a polymer spacer and is either spaced from the corresponding surface of the opposite surfaces of the pixel arrangement a distance substantially not exceeding 50 μm or is in physical contact with the respective surface. The device also comprises a light source system operable to produce an incident light beam of a predetermined cross section corresponding to the size of an active surface of the SLM pixel arrangement; and a magnification optics.
