    Abstract: A system is provided comprising: a light field emanating from a scene and a positive imaging lens focusing light from the light field onto a DMD array. A first collector lens directs the spatially modulated light to a first photodetector having a spectral sensitivity to a first spectral band. The first photodetector senses the directed light from the first pixel-wise multiplication and produces a signal representing a first inner product between the light incident on the DMD and the first basis function for the first spectral band. A second collector lens directs the spatially modulated light to a second photodetector having a spectral sensitivity to a second spectral band. The second photodetector senses the directed light from the first pixel-wise multiplication and produces a signal representing a first inner product between the light incident on the DMD and the first basis function for the second spectral band.

    Abstract: 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.

    Abstract: An apparatus and a method for scanning a surface of an article such as a wooden piece transported along a travel path axis, are capable of generating two complementary color image frames representing the surface of the article in an efficient way. While the sensing field of an imaging sensor is directed transversely toward the travel path axis, a first linear-shaped light beam characterized by a first wavelength is directed toward the scanning zone to form a first reflected line onto the article surface. A second linear-shaped light beam characterized by a second wavelength is directed toward the scanning zone to form a second reflected line onto the article surface. The first and second light sources are activated alternately according to a predetermined frequency, so that the imaging sensor is caused to capture alternately the first and second reflected lines to produce interlaced sequences of reflected intensity image data, which are then separated to generate two complementary color image frames representing the surface of the article.
