An illumination system (10) for exposing a xerographic printing apparatus (12). The system (10) includes a DMD-type imaging spatial light modulator (46), and a DMD-type optical switch (26) for modulating the intensity of the source light (15) irradiating the imaging DMD (46). A single conventional continuous wave tungsten lamp (14) is implemented with its light energy directed by a condensing lens (20) onto the DMD optical switch (26). The DMD optical switch (26) modulates the incident light (15), and passes reflected light to a light integrator (38), which in turn homogenizes and increases the aspect ratio of the light. The light integrator (38) directs the homogenized light via an anamorphic lens (40) onto the imaging DMD (46). The light energy provided to the imaging DMD (46) is precisely modulated in intensity, while remaining uniformly disbursed. The combination incandescent lamp (14) and optical DMD switch (26) offers a low cost, high-intensity alternative to LED arrays.

An optical guide (10, 40, 50, 60) for horizontally aligning two vertically stacked images generated by one or two SLMs. The optical guide has a channel separator (10a) that directs both images along two different paths. A pair of aligning reflectors (10b and 10c) on each path vertically shift the images with respect to each other so that at least part of the images on the first path are aligned side-by-side with at least part of the images on the second path. The channel separator (10a) then re-directs the images to the image plane 15. Along both paths, at least two of the reflecting surfaces of channel separator (10a) or aligning reflectors (10b and 10c) are optically powered so as to change the width or height of the images.

A translucent hemispherical diffuser provides shadowless, uniform illumination of an object to be inspected or otherwise viewed. The optical medium of the translucent diffuser has a milk glass optical consistency, and/or one or more surfaces of the diffuser may be textured to diffuse light entering or leaving the optical medium of the diffuser. The hemispherical diffuser is placed between a light source and the object to be viewed. Light from the light source entering the optical medium of the diffuser is re-radiated uniformly from the concave surface of the diffuser. The object to be viewed is located approximately at the center of curvature of the hemispherical diffuser. Thus, the radiating concave surface of the diffuser subtends a solid angle of approximately two -pi steradians. Light may be scattered and diffused by various reflecting surfaces external to the diffuser, prior to entering the optical medium of the diffuser. One embodiment of the diffuser includes reflecting surfaces as an integral part of the diffuser.

Variations on the Koehler illumination system, used for providing light to be reflected from, or transmitted by, an SLM. An anamorphic illumination system (10) uses multiple light sources (11) and a cylindrical lens (14) to provide an elongated and compressed beam to the SLM (16). A cascaded illumination system (30) uses multiple light sources (31) and multiple TIR prisms (33) to provide an extended light beam or one that is more intense, to the SLM (36).

A spherical illuminator (10, 40, 50, 60) having an upper diffuser (17, 47, 56, 62) with a concave surface, and having either an opposing reflector (18, 41) or an opposing lower diffuser (57, 63) with a concave surface. The two concave surfaces are placed so that their concavities form a substantially spherical viewing area into which the object under inspection is placed. The upper diffuser (10, 40, 50, 60) has a viewing aperture. It transmits light uniformly to the object from approximately two-pi steradians. The reflector (18, 41) or the lower diffuser (57, 63) provides light to the object in another two-pi steradians, resulting in nearly four-pi steradians of illumination.

A non-invasive inspection system is disclosed. The system contains light sources or source, viewing optics, an x-y table, and a platen for mounting objects to be inspected. The transparent platen contains a vacuum system that sets up a laminar flow of air which in turn holds the objects in place without altering or damaging the devices, and allows for analysis of light transmitted through devices. The method for operating the system is also included.
