    Abstract: A detector, feedback and compensation system for use with a radiation distribution system (30) for distributing the radiation from a radiation system (5) to two or more arrays of individually controllable elements, each for patterning beams of radiation, which are subsequently projected onto a substrate (9). The detector determines the radiation lost in the radiation distribution system and feeds this information back to a compensation system, which compensates for the loss and keeps the radiation projected onto the substrate uniform.

    Abstract: A system and method is used to pattern a substrate (18). A projection beam (10) received from a radiation system is patterned using an array of individually controllable elements (13). Each element of a first array of focusing elements (12) directs a portion of the projection beam directly onto one of the individually controllable elements and collects radiation reflected therefrom. An image of the first array of focusing elements (12) is projected onto a second array of focusing elements (17) using a projection system (14,16), such that radiation reflected from one of the individually controllable elements is projected via one of the focusing elements in the first array of focusing elements (12) and the projection system (14,16) to one of the focusing elements in the second array (17) which focuses the radiation onto a spot on the substrate.
