An imaging apparatus () for generating an image signal from incident light with higher spatial frequencies of the incident light limited to reduce undersampling artifacts. Apparatus () includes a detector plane () for generating the image signal from an array of photosites, () and an optical section having a relatively thin lithium niobate rhomboidal filter () interposed in the path of the incident light so as to produce a blurred image on the photosites. A filter configuration is disclosed which produces four spots () at the imaging sensors () positioned at the corners of a rhombus.

Anti-aliasing low-pass blur filter for reducing artifacts in imaging apparatus

A modulator for a high optical power printing includes a transparent crystal and a patterned buffer layer formed over one of the surfaces of the crystal. An electrode array is formed so that each electrode of the electrode array is patterned directly on each portion of the patterned buffer layer. In a further feature of the invention, the crystal substrate can be formed so that opposing endfaces through which high optical power laser light passes are at an angle and are antireflection coated. A transparent and electrically insulating overcoat is provided above the electrodes.
