A superresolution electro-optic imaging system operates in a manner that takes into account the different subsystems For example, rather than designing the optical subsystem to be diffraction-limited, the optical subsystem can be designed in a manner that is better suited for subsequent superresolution processing and/or that reduces aliasing effects

End-to-end design of superresolution electro-optic imaging systems

The present invention relates to various optical elements, related manufacturing methods and systems incorporating the optical elements.

Optical elements related manufacturing methods and assemblies incorporating optical elements

A method and apparatus satisfying growing demands for improving the precision of angle of incidence of implanting ions that impact a semiconductor wafer and the precision of ribbon ion beams for uniform doping of wafers as they pass under an ion beam. The method and apparatus are directed to the design and combination together of novel magnetic ion-optical transport elements for implantation purposes. The design of the optical elements makes possible: (1) Broad-range adjustment of the width of a ribbon beam at the work piece; (2) Correction of inaccuracies in the intensity distribution across the width of a ribbon beam; (3) Independent steering about both X and Y axes; (4) Angle of incidence correction at the work piece; and (5) Approximate compensation for the beam expansion effects arising from space charge. In a practical situation, combinations of the elements allow ribbon beam expansion between source and work piece to 350 millimeter, with good uniformity and angular accuracy. Also, the method and apparatus may be used for introducing quadrupole fields along a beam line.

Controlling the characteristics of implanter ion-beams

Techniques are disclosed of obtaining three-dimensional information pertaining to an object of interest, based on a light-pattern image acquired by digitally photographing the object with patterned light being projected onto the object, By an exemplary technique, a local adaptive spatial-filter is configured for the light-pattern image, based on a spatial frequency characteristic of the light-pattern image having a plurality of sub-areas, on a sub-area-by-sub-area basis, and local thresholds are set for the light-pattern image, based on image information acquired by locally applying the spatial filter to the light-pattern image, on a sub-area-by-sub-area basis.

Three-dimensional object information acquisition using patterned light projection with optimized image-thresholding

A color still image pickup device which enables display of a high picture quality equivalent to that of a 3-CCD image pickup device at the cost of a single chip image pickup device. A method for picking up color still image is also disclosed. A solid-state image pickup device (33) has an image pickup face on which a large number of photoelectric conversion elements are arranged in a matrix and a color filter (11) which has different color component areas corresponding to the array intervals of the photoelectric conversion elements and is fixed to the front face of the image pickup surface of the device (33). The position at which the light is incident on the device (33) is changed by relatively changing the device (33) and the incident light along the image pickup face in steps of the array intervals of the photoelectric conversion element, and the image data picked up by the device (33) are combined at a plurality of positions changed.

Color still image sensing apparatus and method

The Invention is an image input apparatus equipped with means of image shifting which is capable of inputting images of different resolutions, and enables the transmission band of the spatial filter to be switched in accordance with resolution in order to prevent moire. When a flat transparent refraction plate 22 is inclined relative to the optical axis 10 by which light from the object is introduced, the position where the image is formed on the imaging surface of the CCD 14 is shifted, thus making image shifting possible. High resolution images are obtained by shifting the image a distance shorter than the distance between the photosensitive parts of the CCD 14, and then combining the images. The transmission band of the spatial filter 12 for preventing moire can be switched by changing the relative angles of the double refraction plates 20, 21. The transmission band of the spatial filter 12 is switched to the high frequency side when inputting high resolution images by means of the image shift mechanism 13, thus obtaining images of good resolution.
