摘要： A digital cinema projector (100) for projection of color images onto a display surface comprises a light source (116), which produces a beam of light. Beam-shaping optics (130) homogenize and focus the beam of light and color splitting optics (132) separate focus beam of light into separate color beams. A first modulation optics system comprises a prepolarizer (212), which prepolarizes a first color beam; a wire grid polarization beamsplitter (224), which transmits a first predetermined polarization state of the prepolarized beam; a reflective spatial light modulator (204), which alters the transmitted prepolarized beam with information and reflects the image bearing first color beam through the wire grid polarization beamsplitter (224); and a wire grid polarization analyzer (228), which transmits the image bearing first color beam and attenuates unwanted polarization components. A recombination prism (232) combines the first color beam from the first modulation optical system with other image bearing color beams to create a full color image bearing beam. A projection lens system (150) projects the full color image bearing beam onto the display surface (140).

摘要： A dual resolution printer for printing images on an associated print medium includes: a light source providing a light beam and a focusing lens focusing the light beam and creating a converging light beam having at least one beam waist of at least one wavelength at a first beam waist location. The printer also includes an optical unit movable in and out of the converging light beam and having a corresponding first and second position, respectively. This optical unit, in the second position, reimages the beam waist of the converging light beam created by the focusing lens to a different size second beam waist, at a location substantially the same as the first beam waist location.

摘要： A gas zoom lens of the double Gauss type is disclosed. The lens, at a unity magnification setting, has cavities between the outer lens elements filled with a gas under a first pressure and a central cavity filled with the same gas at a second lower pressure. When the lens is moved to alternate magnification positions, its focal length is adjusted by changing the relative pressure, and hence the refractive index of the gas within the cavities, thereby adjusting the focal length of the lens for the particular magnification.

摘要： According to one aspect of the invention, an apparatus for forming distortion free images comprises: (i) a rotationally symmetric lens system capable of forming a distorted image and of introducing lateral color aberration; (ii) a photosensitive image capture medium capable of capturing the distorted image created by the lens system; (iii) an image storage medium storing the distorted image captured by the image capture medium; (iv) an image buffer medium (area) for holding at least one distorted image stored by the image storage medium; and (v) an image processing unit correcting the distorted image and creating an undistorted image. The image processing unit has information describing distortion and lateral color aberration characteristics of the lens system. The image processing unit calculates, for at most one quadrant of the image, given any ideal radial position of a pixel, the actual radial position of the distorted data pixel from which to retrieve the data. Then the image processing unit moves the data corresponding to the radial value of the pixel with the distorted data to its undistorted pixel location in each quadrant of the image, thereby building a corrected image. The corrected image is stored in the image buffer medium; and then moved from the buffer to the image storage medium.

The lens focuses the light from said light source toward a center of the optical modulator assembly. The unit further includes a base adapted to removably support the light source, the optical modulator assembly and the lens in an optically aligned manner. The base is further adapted to be removably attached onto a receiving structure of a printer, such that an attachment of the base having the optically aligned light source, optical modulator assembly, and lens supported thereon, permits light from the optical modulator assembly to be focussed onto an optical element of the printer.

摘要： A dual format pre-objective scanner (10), for use in a laser printer, having an incident beam (22) from input optics (12) incident on a polygon tower (14) comprised of a first polygon (20) having a first diameter and first number of facets and a second polygon (30) having a second diameter and second number of facets, rotating about an axis (42) common to both first and second polygon. The polygon tower (14) is moved in a vertical direction so that the incident light is directed in a plane approximately perpendicular to the axis rotation of the first and second polygon, at either the first polygon (20) or the second polygon (30). The polygon tower (14) is also moved in a lateral direction approximately perpendicular to the axis (42) of rotation of the polygon tower (14). To change size and formats, the polygon tower (14) is moved simultaneously both vertically and laterally so that incident beams on the facets of the first polygon (20) become incident on the facets of the second polygon (30) at approximately the same distance from a scan lens (16).

摘要： A laser microfilm printer (170) having a telecentric F-theta scan lens (166) with optical resolution for image pixel sizes 1-5 microns for writing on an image-receiving medium (164) comprises a polygon reflector. A laser beam incident on the polygon reflector, has a diameter as measured at the 1/e2 intensity value, which is at least 1.4 times a width of a polygon facet (162) in a scan section of the laser microfilm printer (170). The polygon facet (162), at center of scan position, is in a substantially optically conjugate relationship with the image-receiving medium (164) in a cross-scan section of the laser beam (160). The cross-scan section of the F-theta lens (166) has an absolute value of optical magnification of 0.25 to 0.5 as measured from the facet (168) to the image-receiving medium (164).
