APPARATUS AND METHOD FOR SELECTIVELY IRRADIATING A SURFACE

摘要

A surface (9) is selectively irradiated with a beam of light generated by a light source (1) and directed towards the surface. A spatial light modulator (6, 7) is interposed in the path of the light beam towards the surface and is selectively configurable so as to modulate the light which is incident upon the surface in order that the surface (9) can be selectively irradiated.
