摘要： Embodiments relate to a MEMS device including a scanner rotatable about at least one rotation axis, with the scanner having a characteristic resonant frequency. According to one embodiment, the MEMS device includes drive electronics operable to generate a drive signal that causes the scanner to oscillate at an operational frequency about the at least one rotation axis. The drive signal has a drive frequency selected to be about equal to the characteristic resonant frequency or a sub-harmonic frequency of the characteristic resonant frequency. According to another embodiment, the drive electronics are operable to generate a drive signal having a plurality of drive-signal pulses that moves the scanner at an operational frequency and sensing electronics are operable to sense a position of the scanner only when the drive-signal pulses of the drive signal are not being transmitted by the drive electronics. The MEMS device embodiments may be incorporated in scanned beam imagers, endoscopes, and displays.

摘要： According to embodiments, an image bitmap is modified to compensate for non-idealities in actual beam locations delivered by a scanned beam or laser scanner system compared to desired pixel locations. For a non-ideal actual beam location, pixel values for neighboring desired pixel locations may be used to generate a compensated actual pixel value. According to some embodiments, the compensated actual pixel value may be a weighted average of the neighboring desired pixel values. The weighting factors may be determined from the actual beam location compared to the desired respective pixel locations. The system may compensate for various distortions including optical aberrations and scanning distortion.

摘要： A display system includes an image generator that generates an image and a control circuit that reduces or eliminates the viewer's perception of a visual artifact when the viewer's gaze shifts with respect to the image. For example, such a display system may generate a fill-in light to reduce or eliminate the viewer's perception of flicker or other visual artifacts when the viewer shifts his gaze with respect to an exit pupil through which the generated image is viewed. The system may match the fill-in light's brightness, color, or both the brightness and color to the brightness and/or color of the image.

摘要： A device for image transmission includes a first scanner at a first location and a second scanner at a second location, with an optical fiber linking the scanners. The first scanner scans the first location and couples light from the first location to the optical fiber. The fiber transmits the light to the second location where the second scanner constructs an image of the second location from the light. The two scanners are synchronized so that the constructed image corresponds directly to the scanned scene. The second scanner may be part of a retinal scanner, so that the image is formed directly on the user's retina. In another embodiment, the each of the scanners acts as a transceiver so that imaging is bi-directional.
