Abstract
An optical light diffusing system is provided that includes an optical diffuser that coverts incoming light into diffused light. To prevents mixing light from undesired directions in the diffuser, light form undesired direction is baffled before it reaches the diffuser. Baffling is performed with an array of micro lenses located in the optical path to the diffuser. An array of apertures is located between the array of micro lenses and the optical diffuser. Each micro lens is aligned with a corresponding aperture. The apertures are located substantially in a focal surface of the array of micro lenses. Optical baffles located between the array of micro lenses and the array of apertures, separates optically transparent volumes between different ones of the micro lenses and their corresponding apertures.
