IMAGE PROJECTING DEVICE AND METHOD
First Claim
1. An incident light beam of a predetermined cross section to be incident onto the active surface of a spatial light modulator (SLM) unit formed by an SLM pixel arrangement, said a predetermined cross section of the incident beam corresponding to the size of said active surface;
- and a magnification optics accommodated at the output side of the SLM unit;
the device being characterized in that said SLM unit comprises first and second lens'"'"' arrays at opposite sides of the SLM pixel arrangement, 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 SLM pixels.

Abstract
An image projecting device and method are presented. The device comprises a light source system operable to produce a light beam to impinge onto an active surface of a spatial light modulator (SLM) unit formed by an SLM pixel arrangement; and a magnification optics accommodated at the output side of the SLM unit. The light beam impinging onto the SLM pixel arrangement has a predetermined cross section corresponding to the size of said active surface. The SLM unit comprises first and second lens'"'"' arrays at opposite sides of the pixel arrangement, 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 SLM pixels

23. A method for projecting an image comprising:
-
(a) creating an incident light beam having a predetermined cross section corresponding to a size of an active surface of a spatial light modulator (SLM) unit formed by an SLM pixel arrangement, and directing said incident light beam towards said active surface;
(b) passing said light through the SLM unit having first and second lens'"'"' arrays at opposite sides of the SLM pixel arrangement, each lens in the first array and a respective opposite lens in the second array being associated with a corresponding one of the SLM pixels, concurrently operating the SLM pixel arrangement with an imaging signal representative of an image to be projected;
(c) passing modulated light emerging from the SLM unit rough a magnifying optics to be projected into a projecting surface. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)
