Abstract
An improved method is provided for compensating for pixel site defects of a spatial light modulator ( ) in an imaging apparatus ( ). An image is formed at a first position and directed to a surface ( ). Then, an actuator ( ) shifts the spatial light modulator ( ) over a shift distance to a second position, which is some integer multiple n of the distance between pixels ( ) on the spatial light modulator ( ). A second image is formed on the spatial light modulator ( ), shifted by the shift distance, and directed to the surface ( ). Optionally, dithering is provided with an additional shift of an increment of the distance between pixels ( ).
