摘要： In pattern generating apparatus of the type employing a reciprocating laser beam for scanning a substrate surface, three scan lines are formed simultaneously. During reciprocation in one direction, the beam is deflected upwardly at an angle of arccot (1/3) with respect to the reciprocating direction, and during reciprocation in the opposite direction, the beam is deflected downwardly at an angle of arccot (1/3).

摘要： A facsimile transceiver apparatus is described which includes means for advancing a document to a station at which location the document is line scanned by a laser light beam. A video signal thus formed is transmitted to a remote facsimile apparatus for reproduction of the document. The transceiver further includes an electrostatographic printing station at which station a latent electrostatic image is formed by line scanning a laser light beam over a uniformly charged photoreceptor surface. A means for line scanning at the document scanning station and at the photoreceptor surface includes a laser light source and means for alternatively sweeping the laser light beam across the document at the scanning station or across a charged image retention surface at the printing station. Means are also described for enhancing document feed, resolution, and speed of reproduction.

摘要： To scan a long line of printed information, a fiber-optic lineto-rectangle converter is configured at one end to divide a long scan line into a plurality of shorter segments which are arranged at the opposite end to form an array composed of consecutive segments stacked in parallel. Since the array covers an area instead of a line, a video camera tube scanning the array utilizes more of its useable face area thus improving image resolution for the converted line. To operate a helical bar printer having as many hammers as line segments in the converter, the rectangular image is scanned with a series of horizontal sweeps orthogonal to the line segments. With each sweep, the hammers are fired simultaneously in response to video signals indicative of the light level at corresponding positions in each line segment.

摘要： A process and apparatus are described for flicker-free reproduction, e.g., over a narrow band channel, of a slowly transmitted video telephony picture in which received picture signals are stored and repeatedly made visible on a display screen. The picture storage takes place in a storage tube in which, at the reading out of a given picture signal, the memory at this location is erased. For picture reproduction on a display screen each line stored in a storage plate of the storage tube is read out at high speed, and the picture signals, so obtained, are simultaneously portrayed on the display screen of a picture tube and recorded in an intermediate memory. Subsequently, the signals delayed by the intermediate memory are re-recorded at the same location of the previously read-out line. Thereafter, the next and all further stored lines of each picture are successively read out, reproduced, intermediately stored and re-recorded back in the picture storage tube in the same manner.

摘要： A system for converting infrared radiation in the 8-14 micron region to a real time visual image is disclosed. A lens system focuses the image at an image plane. A plurality of mirrors are disposed between the lens system and the image plane and are rotated about an axis intersecting the optical axis at the entrance pupil. Each mirror is disposed to focus an arcuate segment of the image onto a linear array of detectors located substantially on the axis of rotation as the mirror moves through the optical field of view. The image thus scanned is reconstituted at the target of a vidicon type television camera by the same type of system having mirrors rotated in synchronism with the scanning mirrors, but utilizing light emitters rather than light detectors. The video signal from the television camera is then displayed on a conventional television display tube for visual observation.

摘要： A method and apparatus for eliminating multiple images in an airborne optical scanner which occur because of the widening of the scan path as the scanning beam moves from directly underneath the aircraft toward the horizon on either side of the aircraft, and which causes blurring or loss of resolution for the images falling within two or more scans. The problem is overcome by placing selected apertures in the paths of beams of light modulated by information from associated scanners, so as to restrict to a minimum overlap the paths traced by such beams of light on a photographic recording medium.

摘要： A pattern recognition system wherein an image dissector tube is used to provide a scan of an optical image, which scan, when used to establish the degree of similarity of two patterns or changes occurring in a single pattern, is capable of being modified to produce the maximum information required to establish said similarity or change, such modification being achieved by changing the electronic commands controlling the position and movement of the electronic image of the deflectable photomultiplier such that the size, shape, and position of the scanned area and the size of the effective aperture used to generate the scan is modified by appropriate control circuits (normally used in a feedback mode) to insure that the said modification increases the quantity, accuracy, and processability of the said information, full use being made of all a priori knowledge available to constrain scan size, shape, and position, and effective aperture size to further insure optimum scan parameters to provide the required information in the required form.
