PROGRAMMABLE OPTICAL COMPONENT FOR SPATIALLY CONTROLLING THE INTENSITY OF BEAM OF RADIATION
摘要
<p>A programmable optical component (10) for spatially controlling the intensity of a beam of radiation (b), which component comprises a programmable layer which is divided in programmable elements (4,6,8), characterized in that each programmable element comprises bendable nano-elements (8) which are switchable between a non-bend state (8) and a bend state (8') by means of a driver field. In their bend state the nano-elements absorb radiation. The programmable element may be a switchable diffraction grating or a programmable mask.</p>
