A system (8) and method for controlling an angular coverage of a light beam includes defining a non-uniform angular coverage of a first light beam; altering a first spatial relationship between a first movable transmissive deflector (20) and a first light source (11) in response to the definition; directing a first light beam from the first light source (11) through the first movable transmissive deflector (20) such as to provide a first deflected light beam; and focusing the first deflected light beam, by a first optical focusing element (16), to provide a first focused light beam that is focused onto a first area (17) that is characterized by a location that is substantially indifferent to changes in the first spatial relationship.
