<p>A system and method for controlling an angular coverage of a light beam. The method includes: defining a non-uniform angular coverage of a first light beam; altering a first spatial relationship between a first movable transmissive deflector and a first light source in response to the definition; directing a first light beam from the first light source through the first movable transmissive deflector such as to provide a first deflected light beam; and focusing the first deflected beam, by a first optical focusing element, to provide a first focused light bean that is focused onto a first area that is characterized by a location that is substantially indifferent to changes in the first spatial relationship.</p> |
