摘要： A scanning endoscope, amenable to both rigid and flexible forms, scans a beam of light across a field-of-view, collects light scattered from the scanned beam, detects the scattered light, and produces an image. The endoscope may comprise one or more bodies housing a controller, light sources, and detectors; and a separable tip housing the scanning mechanism. The light sources may include laser emitters that combine their outputs into a polychromatic beam. Light may be emitted in ultraviolet or infrared wavelengths to produce a hyperspectral image. The detectors may be housed distally or at a proximal location with gathered light being transmitted thereto via optical fibers. A plurality of scanning elements may be combined to produce a stereoscopic image or other imaging modalities. The endoscope may include a lubricant delivery system to ease passage through body cavities and reduce trauma to the patient. The imaging components are especially compact, being comprised in some embodiments of a MEMS scanner and optical fibers, lending themselves to interstitial placement between other tip features such as working channels, irrigation ports, etc.

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.
