摘要： An image rotation compensation circuit for use with a CRT (14). The compensation circuit includes a winding (22) which encircles the CRT (14) and is oriented transverse to the path of the electron beam (20). A controller (26) is connected to the winding (22) and drives a current through the winding to create a magnetic field. The direction and magnitude of the current may be adjusted by the user to substantially cancel an external magnetic field and thus eliminate any image rotation caused thereby.

摘要： (D A line deflection voltage regulator (60) develops a regulated scan supply voltage. A line deflection circuit (80) is coupled to the voltage regulator (60) for generating line scanning current in a line deflection winding (L H ). The amplitude of the scanning current is dependent on the magnitude of the regulated scan supply voltage. A high voltage regulator (50) develops a second regulated voltage. A high voltage generator (70) is coupled to the high voltage regulator (50) for generating an ultor output voltage at an ultor terminal (U). The magnitude of the ultor output voltage is dependent on the second regulated voltage. A high voltage control circuit (U2) is coupled in a feedback path between the high voltage generator (70) and the high voltage regulator (50) for developing a first ultor control voltage that is representative of the ultor output voltage to regulate the ultor output voltage. A second ultor control voltage that is representative of fluctuations in the ultor output voltage is developed at a point (V e1 ) within the feedback path. The second control voltage is coupled to the line deflection voltage regulator (60) for varying the regulated scan supply voltage to provide raster width regulation.

摘要： A timbase circuit is desribed for providing a horizontal drive correction waveform to correct for pincushion distortion in which a parabolic correction current is derived by squaring (4) a current proportional to the difference between the instantaneous and average values of the vertical ramp voltage. The correction current may be tilted by combination with a linear current proportional to the ramp voltage (7) and may also be amplitude controlled (16).

摘要： A deflection distortion correcting circuit for CRT displays with interlaced scanning is disclosed, which corrects concurrently both linearity of vertical deflection and pairing of horizontal interlaced scanning lines which is caused by variation in anode voltage. This is achieved by combining an adder (26) with a cubic curve linearity correction circuit (12, 14, 16) to introduce a pairing correcting component related to the variation in anode voltage into the cubic curve linearity correction.

摘要： A method and apparatus used to step and correct the position of raster lines in a sinusoidal or zig-zag deflection system. By combining the magnetic flux generated with a rotation "twister" coil and a vertical deflection coil, scan lines can be uniformly spaced and separated nearly to their ends. Accordingly, the magnetic flux generated with the twister coil is adjusted going in the left to right direction then reversed in polarity and readjusted while returning from right to left. It is this controlled twister flux that combines with the linear vertical deflection flux to straighten and then step each scan line to produce an aligned raster.

摘要： A system for detecting deviations from an optical axis of one or more individual component beams (16, 18, 20) associated with plural laser beams. In the specific embodiment, the system includes a mechanism that automatically corrects (14) the detected deviations of each component beam of the plural beams. A beam pick-off device, such as a pick-off collimating lens or beam splitter (36), redirects a sample of the plural beams, which represents separated plural beams to a color wheel (90). A beam splitter (98) splits the isolated component beam into a first split beam (100) and a second split beam (102) and directs the first split beam and the second split beam along a first optical path that terminates at a first detector (70) and a second optical path that terminates at a second detector (72), respectively. The lengths of the first and second optical paths differ by a predetermined distance. Software running on a computer (92) compares the relative position of the first split beam on the first detector to the position of the second split beam on the second detector with reference to the predetermined distance and provides a beam deviation signal in response thereto.

摘要： A multi channel video engine (10) for accepting, dividing, modifying and recombining light to project an image. A housing (12) encloses an optical assembly (28) having a dichroic mirror assembly (58) and a color cube (60). A plurality of LCD assemblies (30) accept light from the dichroic mirror assembly (58), modifies it, and reflects it to the color cube (60). A lens assembly (16) is affixed to a bulkhead (24) of the housing (12) using a lens cradle (14) and lens retainer (18). An output prism (54) aligns light onto a second plane (70) to coincide with an optical axis (72) of the lens assembly (16).
