Abstract
A system and a method for illuminating a spatial light modulator, where all the pixels of the SLM are illuminated symmetrically with respect to the optical axis, thus reducing the crosstalk problem. The system includes a linear array of light sources for generating a plurality of light beams, a linear array of microlenses, each of the microlenses receiving light from a corresponding light source of the array of light sources, an optical element for receiving light from the array of microlenses and for redirecting it and a spatial light modulator including an array of pixels for modulating the light. The distance between the array of microlenses and the optical element is such that all the pixels of the SLM are illuminated symmetrically with respect to the optical axis of the optical element.
