Latest Patents

One of Jianhua Xu's latest patents is titled "Method and apparatus for phase correction in a scanned beam imager." This invention involves a method for detecting scanner phase error in a bidirectional scanned beam imager. It includes obtaining first and second images derived from respective first and second scan directions, comparing apparent image feature positions in the first and second images, and calculating a phase error corresponding to the difference between these positions. The comparison may involve multiplying frequency domain transformations of the images.

Another significant patent is the "Scanning endoscope." This innovative device is amenable to both rigid and flexible forms. It 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, along with a separable tip housing the scanning mechanism. The light sources may include laser emitters that combine their outputs into a polychromatic beam, emitting light in ultraviolet or infrared wavelengths to produce a hyperspectral image. The imaging components are especially compact, making them suitable for interstitial placement between other tip features.
