Abstract: There is disclosed an adjustable collimator assembly which utilizes a lens barrel member and a housing member which holds a laser diode at a fixed position. A portion of one of these members are received within a portion of the other member. These two members have a coacting member to provide a relative movement between them for adjusting the lens barrel member relative to the laser diode. The potion of the other member which receives the one member has an integral gripping means for gripping the one member to fix the position of the members relative to each other in order to fix the position of the lens barrel relative to the laser diode.

Abstract: A wobble correction lens (10) for a raster output scanner combines a positive cross-scan piano-cylindrical lens (14), which provides most of the optical power for focusing the light beam to a scan line, with a diffractive surface (16), which corrects the cross-scan field curvature of the cross-scan piano-cylindrical lens. The diffractive surface (16) will have a multi-level structure (binary diffractive optical surface) which possesses a diffractive phase function that will flatten the cross-scan field curvature of the piano-cylindrical lens.

Abstract: PROBLEM TO BE SOLVED: To provide a device of a polygon-less raster output scanning system for wide page printing. SOLUTION: A VCSEL laser print bar 100 of which the position is adjustable is used in a dynamic structure, thereby raising a scanning resolution and providing a performance for wide page printing. A beam from a specific light-emitting element 160 is blocked by a light-receiving member 210, is blocked by a plane surface in the vicinity of the light-receiving member 210 and is imaged to a photosensor. The photosensor is positioned such that VCSEL arrays 110 are optimally arranged. An electric signal is fed back to a piezoelectric actuator 143, then the VCSEL arrays 110 are adequately arranged. In the dynamic structure, the feedback signal is used to maintain synchronization between the print bar 100 and a control signal.

Abstract: PROBLEM TO BE SOLVED: To judge an optional laser position along a scanning line and to perform excellent spot positioning by providing a positioning device for moving an apparent source inside a light emitting device. SOLUTION: Light from a light source 104 is coupled to a flexible waveguide 112. One end part of the flexible waveguide 112 is attached to a fixed plate 114 and closely coupled to a laser stripe 106 and the other end part of the flexible waveguide 112 is attached to a movable plate 108. The apparent source 102 is arranged at a position for emitting a light beam from the end part of the flexible waveguide 112 attached to the movable plate 108. The movable plate 108 is connected to actuators 110 and 111, the actuator 110 adjusts the movable plate 108 in a sagittal direction and the actuator 111 adjusts the movable plate 108 in an axial direction.

Abstract: PROBLEM TO BE SOLVED: To provide a low cost optical filtering method and apparatus for image forming error reduction in a multi-beam scanner.
SOLUTION: A printing system includes a multiple-beam generator array 12 configured to generate multiple beams. A collimator lens 16 is positioned to receive the multiple beams 14a and 14b, and an aperture stop 18 is located where the pupil faces of the multiple beams are spatially coincident with each other. A scanning optical system is positioned to receive the beams from the aperture stop, and a recording medium receives the beams from the scanning optical system. A filter 54 is located where pupil faces of the multiple beams are spatially coincident with each other, whereby each of the multiple beams may be filtered by the supplied filter.

Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a three-dimensional MEMS structure. SOLUTION: The method of manufacturing the molded optical MEMS component, having stress thin films has a step of providing the component with a substrate having a surface, a step of adhering a sacrificial layer onto this surface, a step of arranging a lift-off mask on the sacrificial layer in order to delineate the optical MEMS component, a step of adhering a stress gradient layer on the sacrificial layer, a step of removing the lift-off mask and portions of the stress gradient layer existing on the lift-off mask and a step of making the optical MEMS component, by releasing the stress gradient layer from the sacrificial layer.

Abstract: PROBLEM TO BE SOLVED: To provide a system for monitoring a light emitting diode (LED) in a print bar. SOLUTION: In the system for monitoring the light emitting diode (LED) in the print bar, a photosensor 236 is built in a printer or the print bar itself. The photosensor 236 detects the reduction of the intensity of the LED 212 in the print bar as the print bar is being deteriorated so that a driver circuit 204 for supplying a power to each LED 212 can be calibrated again. The calibrated output power of each of the driver circuits 204 compensates the non-uniform LEDs 212 due to the deterioration. COPYRIGHT: (C)2003,JPO
