Abstract: A beam scanning system for scanning an imaging surface includes a phase shifter for issuing phase signals, a radiation emitter for emitting a beam of radiation and a deflection element, such as an acousto-optic modulator or translating lens, for deflecting the radiation beam. Depending on the implementation, the emitter can be configured to phase shift the radiation beam and/or the deflection element can be configured to deflect the radiation beam in accordance with the issued phase signals. By emitting and/or deflecting the radiation beam in accordance with the phase signals, the length of the scan line formed on the imaging surface can be controlled. A deflector, such as a spin mirror or rotatable prism, is provided to direct the radiation beam to form a scan line on the imaging surface.

Abstract: A laser scanning device is disclosed which includes a spinner, one light spot misalignment detector and a beam misalignment corrector. The spinner scans a light beam across a scanning line. The detector is located generally at a beginning of the scanned line and measures an initial misalignment of the light spot in a cross-scanning direction. The corrector dynamically corrects, during scanning along said scanning line, the scanning misalignment of the light beam in accordance with at least the initial misalignment. The corrector includes a pre-positioner which determines an offset for the initial misalignment, a pyramidal error estimator which estimates a first portion of the misalignment due to pyramidal error and a wobble estimator which estimate a second portion of the misalignment caused by wobble. The estimations are summed together and used for correcting the misalignment.

Abstract: A raster output scanning system is disclosed which utilizes a single light source, an electro-optical device and a beam-splitter to generate two partially overlapping light beams in order to scan one scan line in which the width of the scan line can be adjusted electronically. The two partially overlapping light beams in effect generate a resulting light beam. By changing the polarization factor of the electro-optical device, the intensities of the two light beams can be modified which in turn will change the width of the resulting light beam and as a result the spot size changes. By changing the spot size, the width of the scan line can be adjusted. Also, by changing the polarization factor, the position of the resulting light beam can be changed.

Abstract: An optical printer, suitable for use in printing upon a recording medium, includes a tubular compensator disposed between a print head and the recording medium. The print head directs an elongated exposing beam through the compensator to impinge upon the medium, and the beam effects a line exposure across the medium. A transport device introduces relative motion between the medium and the print head during a line exposure by the beam. The relative motion is perpendicular to the exposure line and introduces a smear to each exposure line as well as an overlap between exposure lines. The tubular compensator includes inner and outer cylindrical surfaces having centers of curvature displaced relative to each other resulting in a wedge-like cross-section to a wall of the tubular compensator. The wedge angle varies with rotation of the compensator to provide for a linear deflection of the beam during a line exposure by the beam, thereby offsetting the advancement of the medium during the line exposure.

Abstract: An image forming apparatus for forming an image by deflecting a light beam signal modulated by an image signal onto a photoconductive element by a polygonal mirror to electrostatically form a latent image and developing the latent image. A main scanning synchronization detector is located in the vicinity of the photoconductive element for setting up synchronization in the main scanning direction. A displacement detector detects a distance over which the photoconductive element has been displaced over a period of time associated with a subscanning pitch. Correcting control is driven in response to the output signals of the main scanning synchronization detector and displacement detector. The light beam signal is so deflected in the subscanning direction as to correct an error in the subscanning pitch.

Abstract: A scanning system device has a predetermined aberration as it scans or switches light along selected optical paths. A deformable membrane receives the light and introduces an inverse “aberration” that offsets that of the scanning system. In one embodiment the scanning system includes a torsion arm that supports an oscillatory body. The torsion arm and/or body can be machined from metal, micromachined in silicon or formed in a variety of other ways. Alternatively, the scanning system may include a rotating polygonal scanner or other type of optical scanner. In another approach, an optical switch replaces the scanner.
