摘要:
A method of exposing an integral imaging element having: an integral lens sheet with opposed front and back surfaces; and a light sensitive layer positioned behind the back surface; the method comprising the steps of: exposing the light sensitive layer with light from behind the back surface;wherein the element additionally has an anti-halation layer on at least a portion of the front surface of the lens sheet which anti-halation layer, during exposure, reduces the amount of exposing light which would otherwise be reflected back toward the light sensitive layer from the front surface. A system which can use the above method, and an integral image element of a type which can be produced by it, are also described.

A lenticular print (13) having image bundles (19), and method and apparatus for aligning and centering image bundles (19) in the print (13) under lenticules in a lenticular overlay (11). On the print are provided one or more two-dimensional fiducial indicia (17) containing one or more angular or linear alignment elements (18, 29, 45) disposed at about two lenticules widths apart.

An apparatus and method for obtaining an image of an object. The apparatus comprises a radiation source and a series of two to five linear detectors spaced therefrom to define a scanning zone; means to cause an object to move relative to and through the scanning zone; a direct image generation apparatus to generate an image from the output of a linear detector; an intermediate image generation apparatus configured to generate at least one intermediate image from an adjacent pair of linear detectors, by processing the output of the pair of detectors and generating an image representative of an output intermediate between the two said detector outputs; the image apparatus adapted such that at least five and preferably at least six images are generated in total; an image display adapted successively to display such images and thus display the monocular movement parallax between the images.

Method and apparatus for stereoscopic images using a viewing grid and not requiring a lenticular viewing screen. In one embodiment applied to roentgenography, the apparatus includes an X-ray source, a table or cradle disposed beneath the X-ray source for securing an image subject such as a patient, and a recording medium cassette disposed beneath the table or cradle. The cassette includes a film comprising a base, an emulsion on a first side of the base and a viewing grid on an opposite second side of the base, an image intensifying screen for exposing the emulsion films for recording an image, and a recording grid located between the phosphorous screen and the emulsion side of the film, and fixed in position relative to the image intensifying screen for masking a plurality of strips of predetermined width, of the emulsion film. During exposure, relative movement between the cradle and cassette is maintained so as to capture various views of the image subject on the emulsion film. Where tomographic images are recorded, frontal and rear view stereoscopic images can be visualized on opposite sides of the film, respectively.
摘要:
A method for printing interdigitated images comprising the steps of interdigitating f images by modulating b beams of light (12) with image information. The b beams of light (12) are scanned onto an image-forming medium (50) by a polygon scanner (30) which has p sides. The relationship between the number of images f, the beams of light b, and the number of sides of the polygon p is given by f/pb=n where n is an integer. The image-forming medium is registered with a lenticular medium.

The present invention is directed to an apparatus and an associated method for achieving alignment between an image on a film and a lenticular material that is to be bonded to the film to permit the image to be viewed in 3D. The apparatus imparts a controlled bending of the lenticular material over the film such that the slight differences in length between the lenticular material and the film, caused by the bending, adjusts for changes in the line spacing of the lenticular material and or in the spacing of the image segments. Other embodiments of the invention provide for a controlled stretching of the film along its length and from side-to-side to again compensate for variations in the line spacing of the lenticular material or spacing of the image segments.
