    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： A MEMS scanning device includes more than one type of actuation. In one approach capacitive and magnetic drives combine to move a portion of the device along a common path. In one such structure, the capacitive drive comes from interleaved combs. In another approach, a comb drive combines with a pair of planar electrodes to produce rotation of a central body relative to a substrate. In an optical scanning application, the central body is a mirror. In a biaxial structure, a gimbal ring carries the central body. The gimbal ring may be driven by more than one type of actuation to produce motion about an axis orthogonal to that of the central body. In another aspect, a MEMS scanning device is constructed with a reduced footprint.

    摘要： A laser drive controller compensates for temperature-dependent effects of a temperature-sensitive laser. Temperature variations in the laser may be measured and/or predicted based on variable pulsed output. The controller may drive the laser to maintain temperature and/or to compensate for variations in temperature. The techniques may be applied to a laser scanner, scanned beam display, laser printer, laser camera, scanned beam imager, etc.

    摘要： A variable illuminator, for instance a device for scanning a beam of light, emits a selected amount of power to a plurality of spots across a field of view. The amount of power is determined as inversely proportional to the apparent brightness of each spot. In the case where the spot size is equal to pixel size, the device may operate with a non-imaging detector. In the case where pixel size substantially equals spot size, the output of the variable illuminator may be converged to produce a substantially uniform detector response and the image information is determined as the inverse of a frame buffer used to drive the variable illuminator. The illuminator and detector may be driven synchronously. In the case where an imaging detector is used, the variable illumination may be used to compress the dynamic range of the field of view to substantially within the dynamic range of the imaging detector.
