Abstract
A system and method for projecting images including an illumination light beam (emitted by a source) and a collimated light beam (emitted by a laser source). The two light beams being combined into one light via a microlens array combined with a pinhole matrix located in the focal plane of the microlens array. The collimated beam is transmitted through this array and the base beam is reflected therefrom.
