摘要： Disclosed is a method for processing input information and recordding the processed information in the form of "distributed data pattern", where the printed distributed data pattern can be reprocessed in order to reconstruct the input information. The input information is not directly visible in the printed distributed pattern data. The method has the characteristic that each portion of the input information contributes to all portions of the printed distributed data pattern. Similarly the reprocessing has the characteristic that all portions of the printed distributed data pattern contribute to each portion of the reconstructed input information.

摘要： A reading device (400) to aid in viewing the image to be produced by illuminating a diffractive optical surface (100) to produce a diffracted beam. The device (400) includes a light source (402) to produce a laser beam which is directed through a lens system (403). The beam is directed to and illuminates a diffractive optical surface to produce a diffractive beam. The diffractive beam is intercepted by an image receiving surface (409). A user of the device could then view the image on the image receiving surface (409). To configure the machine (400) to provide a focused image onthe image receiving surface (409), a mirror is placed at the position of the diffractive surface to produce a "spot" on the surface (409), which spot can then be adjusted in respect of size and focus. This is achieved by altering the lens system and position at which it is engaged by the laser beam.

摘要： A diffraction surface (100) and a method of making the surface. The surface (100) may be applied to labels and other items, to identify the origin of the goods to which the label is attached. The surface (100) can include a block grating. For example, the surface could include a plurality of blocks (350) which adapted when illuminated will produce a recognisable image on an intercepting surface. The diffraction grating is manufactured by processing a data stream indicative of the image. Processing of the data stream includes obtaining a Fourier Transform of the data stream. Preferably, the data stream is clipped and quantised.

摘要： A diffraction surface (10) and a method of making the surface. The surface (10) may be applied to labels and other items to identify the origin of the goods to which the label is attached. The surface (10) can include a block grating including ridges (11, 13) and recesses (15) in the enclosed squares or rectangles. The diffraction grating (10) is manufactured by processing a data stream indicative of the image, including obtaining a Fourier Transform of the data stream and preferably clipping and quantising the data stream, and deforming a plate surface in accordance with the data stream. Also claimed is a diffraction grating having spaced first and second portions each producing an image on a receiving surface in response to illumination by a reading light beam, configured such that when the reading light beam moves from the first to the second portion, a change occurs in the first image to produce the second image.

摘要： A method and apparatus (301) for detecting information stored on an optical memory diffraction surface (101). A reading light beam (102) illuminates the surface (101). At least one diffracted light beam (104) is produced, with the light beam (104) having a predetermined intensity pattern. A sensor (309) is illuminated by a diffracted beam (308) and is used for authentication purposes. A second sensor (319) is illuminated by a second diffracted beam (308), which second beam (308) passes through an optical lens (imaging lens) (304) so that an image is produced on the sensor (319). The sensor (309) produces a signal for authentication purposes which signal can be compared to a "template" signal. The signal generated by the sensor (319) has additional information to that information contained in the signal produced by the sensor (309).

摘要： Optical Image Authenticator and method where a light intensity pixel array is detected and compared with a reference pixel array on a pixel by pixel basis to determine if each pixel is either good or bad. Authentication is done on the basis of the number of good/bad pixel's or their ratio. Pixel's are assigned a grey scale value or a binary value. Values are allocated with respect to different threshold levels. The optical memory can be a pixilated diffraction grating or "pixelgram". Detection is via a CCD sensor and a laser pulses every frame. Detected pattern starting point position is matched with the respective positions in the authentic pattern. The authentic pattern is stored in a variety of forms which have been rotated or linearly translated. For use in the field of securities and credit cards.
