| Number | Title | Issue Date |
| 5986778 | Hologon deflector system having dispersive optical elements for scan line bow correction, wavelength shift correction and scanning spot ellipticity correction Bow can be minimized by an auxiliary grating in a post deflection path of the diffracted beam from the hologon which is disposed in non-parallel relationship to the plane of rotation of the hologon. The ellipticity of the spot which generates the scan lin... | 11/16/1999 |
| 5481384 | Deflector system which produces dual, oppositely directed scanning beams simultaneously or successively Centered monofacet deflector systems having a dipole laser beam scanning pattern (dual scanning beams which propagate in opposite directions) enables both the scan rate and the scan duty cycle of the scanning system to be doubled over deflectors which pro... | 01/02/1996 |
| 5367399 | Rotationally symmetric dual reflection optical beam scanner and system using same A dual reflection unpolarizing monofacet (DRUM) scanner or beam deflector is made up of two essentially identical 45° right angle prism elements with their hypotenuse faces together to form a body which may be rectangular or cylindrical and may be contai... | 11/22/1994 |
| 5223956 | Optical beam scanners for imaging applications Laser beam scanners having a polarization sensitive beam deflecting surface (specifically a monofacet nondisc plane diffraction grating (NPDG) monofacet deflector and a dual reflection monofacet polarization sensitive deflector that incorporates a polariz... | 06/29/1993 |
| 5183350 | Adjustable fixed mount for a hologon deflector An adjustable, resettable fixed mount for a hologon laser scanner disc or spinner provides perpendicular angular orientation of the hologon disc relative to the motor rotation axis within about 5 to 10 arc seconds and corresponding wobble angles as compar... | 02/02/1993 |
| 5179463 | Simultaneous multibeam scanning system A dual, simultaneous beam scanning system for simultaneously scanning two individually modulated adjacent scan lines on an internal drum imaging surface uses a deflector which varies the angular orientation between combined orthogonally polarized beams so... | 01/12/1993 |
| 5046794 | Hologon scanner system A hologon scanning system which provides two sequential scans across an image plane per revolution of the hologon. The hologon is a disc having a single facet with a planar linear diffraction grating in a surface which is perpendicular to the axis of rota... | 09/10/1991 |
| 4973112 | Hologon deflection system having dispersive optical elements for scan line bow correction, wavelength shift correction and scanning spot ellipticity correction Bow can be minimized by an auxiliary grating in the post deflection path of a diffracted beam from the hologon which is disposed in non-parallel relationship to the plane of rotation of the hologon. The ellipticity of the spot which generates the scan lin... | 11/27/1990 |
| 4852956 | Hologan scanner system A hologon scanning system which generates an essentially bow-free scan line or lines across a surface using a planar, and preferably a holographic, grating disposed in a holding assembly which is rotated about an axis. The surface of the grating is at a c... | 08/01/1989 |
| 4779944 | Integrated laser beam scanning system An integrated laser scanning system for scanning a modulated beam across an image surface, which may be a receptor on which the image is scanned, is provided by a rigid housing having a central plate and walls which define a plurality of cells on opposite... | 10/25/1988 |
| 4610500 | Hologon laser scanner apparatus A unitary assembly of a hologon scanner disc or spinner, a motor for rotating the disc and a lens for focusing the deflected laser beam on an image surface. A housing including a base plate and a cover removably mounted on the base plate, encloses the hol... | 09/09/1986 |
| 4583816 | Preobjective hologon scanner system A hologon scanner system in which a laser beam is scanned across a receptor surface with an essentially bow-free scan. A focusing lens comprised of symmetrical, nonanamorphic optical elements is positioned in the scanned beam between the hologon deflector... | 04/22/1986 |
