  • Publication number: 20190297245
    Abstract: An imaging device may include a first illumination port to output first light having a first illumination distribution at a target to illuminate the target, a second illumination port to output second light having a second illumination distribution at the target to illuminate the target, the second illumination distribution being substantially similar to the first illumination distribution at the target, the second illumination port being spaced apart from the first illumination port, the first and second illumination distributions being simultaneously provided to the target and overlapping at the target. The illumination from the first and second ports may be matched to a same aspect ratio and field of view coverage as the imaging field of view.

  • Patent number: 10169862
    Abstract: Methods and systems for imaging tissue of a subject are disclosed, and involve illuminating the tissue with a coherent light having a coherent wavelength, acquiring image data of the tissue using a color image sensor, and processing the image data using laser speckle contrast analysis while correcting for differences in sensitivity of color pixels at the coherent wavelength to generate a perfusion image of the tissue. The perfusion image is then displayed to the user. Also disclosed are methods and systems for correcting for ambient light and for acquiring white light images along with laser speckle images.

  • Publication number: 20180234603
    Abstract: An imaging device having an imaging field of view, the imaging device including at least one illumination port configured to output light for illuminating a target; an imaging sensor to detect light traveling along an optical path to the imaging sensor; and a first movable window positioned upstream of the sensor with respect to a direction of travel of light along the optical path, wherein the first movable window is configured to move into the optical path in a deployed position for modifying light received from the target.

  • Publication number: 20170354392
    Abstract: Adaptive imaging methods and systems for generating enhanced low light video of an object for medical visualization are disclosed and include acquiring, with an image acquisition assembly, a sequence of reference frames and/or a sequence of low light video frames depicting the object, assessing relative movement between the image acquisition assembly and the object based on at least a portion of the acquired sequence of reference video frames or the acquired sequence of low light video frames, adjusting a level of image processing of the low light video frames based at least in part on the relative movement between the image acquisition assembly and the object, and generating a characteristic low light video output from a quantity of the low light video frames, wherein the quantity of the low light video frames is based on the adjusted level of image processing of the low light video frames.
