FACSIMILE REPRODUCTION SYSTEM

A facsimile reproduction system is disclosed. The system utilizes a laser beam at the transmission station to scan across an image to be reproduced through an acousto-optic modulator (AOM) cell. The laser beam is reflected off the image onto photo detector cells to generate electrical signals analagous to tonal variation in the image. A laser beam at the receiver station is also provided to sensitize a sheet of sensitized paper to produce a facsimile of the image. The intensity of the receiving station laser beam is modulated in accordance with the photo detector electrical signals by applying the signals to an rf carrier which then is applied to an AOM cell positioned between the laser and sensitized paper. Both the transmission and reception laser beams are rapidly deflected by modulating the frequency of the rf carrier driving the respective AOM cells so that the intensity of the effective scanning profile (perpendicular to the direction of scan) is constant across the entire width of ...

Imaging module and reader for, and method of, reading a target by image capture with a visually enhanced aiming light pattern

An imaging sensor of an imaging reader senses return light from a target to be read by image capture along an imaging axis over a field of view that extends along mutually orthogonal, horizontal and vertical axes. Two aiming light assemblies are offset from the sensor, and direct an aiming light pattern at the target. The pattern has an aiming mark in a central area of the pattern, and a pair of aiming light lines that are collinear along the horizontal axis. The visibility of the aiming mark is enhanced by optically configuring the aiming mark to be different in brightness and/or color and/or size and/or state of existence relative to a remaining area of the pattern. The aiming mark of enhanced visibility constitutes a prominent visual indicator of a center zone of the field of view.

LASER OPERATED SCANNING AND PRINTING SYSTEM

A scanning and printing system scans and digitizes graphical information for recording on magnetic tape and also prints graphical information previously stored in digital form on a magnetic tape. Scanning and printing is accomplished by directing a laser beam through a pinhole in an aperture plate and thence through a set of optics, which collimate the beam and scan it across the surface of a graphic medium. For operation as a printer the laser beam is addressed by an accousto-optic modulator, which is positioned between the laser and the aperture plate.
