摘要： A scan assembly of an image generator sweeps an image beam in a first dimension at a first rate and bi-directionally in a second dimension at a slower rate. Sweeping the beam bi-directionally in the vertical dimension (generally the dimension of the lower sweep rate) can reduce the scanning power by eliminating the flyback period, and, where the scan assembly includes a mechanical reflector, can reduce the error in the beam position without a feedback loop by reducing the number of harmonics in the vertical sweep function. Furthermore, because the image beam is “on” longer due to the elimination of the flyback period, the scanned image is often brighter for a given beam intensity. The scan assembly may also sweep the image beam non-linearly in the vertical dimension, and this sweep may be bi-directional or uni-directional. Sweeping the beam non-linearly can also reduce the error in the beam position by reducing the number of harmonics in the vertical sweep function.

摘要： A scanned light display system includes a light source operable to emit light and a curved mirror positioned to receive at least a portion of the light. The curved mirror is configured to substantially collimate the received light. The substantially collimated light is scanned to form an image by moving at least one of the light source and the curved mirror relative to each other. Alternatively, the scanned light display system includes a light source operable to emit light, a curved mirror positioned to receive some of the light, and an optical element positioned to receive light reflected from the curved mirror. The optical element is configured to substantially collimate the reflected light. The substantially collimated light is scanned to form an image by moving at least one of the light source, the curved mirror, and the optical element. Scanning mirror assemblies and methods of making are also disclosed.

摘要： A circuit for detecting a phase error between a clock signal and a beam position includes a beam generator, a sensor, and a phase detector. The beam generator directs a beam toward a beam sweeper in response to the clock signal, and the sensor detects the beam as directed from the beam sweeper. The phase detector determines from the detected beam the error in the clock phase relative to the beam position. Such a circuit can automatically detect the phase error in the pixel clock and correct this error, thus eliminating the need for a manual phase-error corrector. The circuit may also be able to adjust the width and/or the height of a scan region, and thus may also be able to adjust the width and/or height of an image frame within the scan region.

摘要： An image generation apparatus provides interpolation and distortion correction. The interpolation and distortion correction may be provided in one or two dimensions. Nonlinear image scan trajectories, such as sinusoidal and bi-sinusoidal trajectories are accommodated. Horizontal and vertical scan positions are determined using a linear pixel clock, and displayed pixel intensities are determined using interpolation techniques.

摘要： A scan assembly includes an emitter array containing a plurality of optical emitters. Each optical emitter generates a corresponding image beam and the scan assembly scans the image beams in a plurality of overlapping display zones. The overlap of adjacent image display zones forms blending zones and the scan assembly can modulate the intensities of the image beams as a function of the position of the image beams in the blending zones. This modulation for a given blending zone may be a linearly increasing intensity of a first image beam and a linearly decreasing intensity of a second image beam.
