摘要： A multibeam scanner for scanning an image area with a plurality of laser beams, comprising a plurality of beam emitting points that emit a plurality of laser beams reaching the image area with respective time lags therebetween, a time lag determination unit that determines at least one of the time lags during a predetermined calculation time, a scan controller that controls the plurality of beam emitting points to emit the plurality of laser beams successively in the image area with the at least one of the time lags determined by the time lag determination unit. The multibeam scanner of the invention, comprises a photodetector that detects any one of the laser beams at a predetermined beam detection position. The time lag determination unit determines the time lag between the nth laser beam and the nnull1th laser beam. Therefore, to scan the image area, the photodetector detects the first laser beam at the predetermined beam detection position, prior to the image area, and determines a scan start time for the first laser beam. Then, the scan controller starts controlling the first beam emitting point at the determined scan start time to emit the first laser beam in the image area. The scan controller further controls the nnull1th beam emitting point to emit the nth laser beam in the image area with the calculated time lag between the nth laser beam and the nnull1th laser beam.

摘要： A multi-beam optical system has a beam-dividing element that divides a light beam emitted by a light source into a plurality of light beams, which are emerged therefrom at different angles, respectively. A propagation optical system, through which the divided light beams propagate, includes a plurality of curved surface mirrors, and an image-forming optical system that forms a plurality of beam spots on an objective surface by converging the light beams propagated through the propagation optical system. In such an optical system, the curved mirrors are arranged such that the affection of the mirrors on the alignment of the beam spots is accumulatively cancelled.

摘要： An optical scanning device has an incident optical system that makes a light beam emitted from a light source unit enter to a deflection surface of an optical deflector in a state in which the light beam has a larger width than a width of the deflection surface in a main scanning direction, and an imaging optical system that images the light beam reflectively deflected by the optical deflector onto a surface to be scanned. In the device, a slit member that restricts a diameter of the light beam in a sub-scanning direction is provided within an optical path between the optical deflector and the surface to be scanned. A peak intensity of a spot of the light beam scanned on the surface to be scanned is made constant, or substantially constant across an entire effective scanning region. A dependence on an angle of view of the peak intensity of the spot in the scanning optical system can thus be reduced, in particular, minute printing across an entire effective scanning region can be obtained even in a high-speed optical scanning device using an overfilled scanning optical system.

摘要： An optical scanning device, a correction method of the position of an image, an image display method, and an image display device able to improve a light projection efficiency and lower the electric power and able to reduce error of the projection image along with an increase in efficiency of light projection in an image display device for scanning by a one-dimensional image to generate a two-dimensional image are provided. In the image display device, a scanning means (2) scans in both an outgoing path and a return path direction to project the light. The image display device is provided with an angle sensor 16 for reading the angle of the scanning means (2) and a position sensitive detector (15) for detecting the position of the projection light. A system control circuit (10) processes the obtained angle data and position data at an angle data correction unit (13) and a light position detection unit (14) to determine the phase delay of the output of the angle sensor (16) and adjusts a modulation/projection timing so as to correct the phase delay and match the positions of the image projected in the outgoing path and the return path.

The piezoelectric elements are made to deflect in opposite directions upon the application of the electrical signal to cause the platform to pivot. Applying voltages of the opposite polarity causes the platform to pivot in the opposite direction. A mirror may be attached to the platform to produce a scanning mirror for the vertical deflection of a television image.

摘要： An optical deflector comprises a control means for controlling at least either a light source or a deflection means adapted to gauge the distance between the position of a deflected beam of light moving on a light receiving element in one direction and the position of another deflected beam of light moving on the light receiving element in the opposite direction and control the distance so as to make it agree with a predetermined value. Thus, the optical deflector can very accurately control the operation of the deflection means in such a way that it is not affected by changes of environmental temperature of the deflection means and the detection circuit, because a detection means for detecting the time when a beam of light passes by a predetermined angle of deflection of the deflection means is not used.
