Abstract: A dynamic imaging system for use with endoscope, or as an element of a video endoscope, utilizes path length differences and/or a variable aperture size to expand a usable depth of field and/or improve image resolution in an area of interest in the image field. In some implementations, the imaging system utilizes a variable aperture in conjunction with unequally spaced image sensors placed downstream from a beam splitter. An imaging system captures multiple focal planes of an image scene on separate sensors. A variable aperture permits the capture of enhanced resolution images or images with longer depths of field. These differently focused images and/or images with different resolutions and depths of field are then combined using image fusion techniques.

Abstract: A trocar is provided that is adapted to insert a lighting attachment into a body cavity. The trocar connects at its distal end to the lighting attachment such that it can be pushed into the body cavity. An endoscope may then be inserted through the trocar into the body cavity. The lighting attachment is configured to detach from the trocar and attach to the endoscope head to provide additional lighting to the endoscope. The lighting attachment includes foldable lighting panels that expand when in use in order to light a wider field of view. The lighting attachment may be powered by induction coil from the endoscope.

Abstract: A dynamic imaging system of an endoscope that adjusts path length differences or focal points to expand a usable depth of field. The imaging system utilizes a variable lens to adjust the focal plane of the beam or an actuated sensor to adjust the detected focal plane. The imaging system is thus capable of capturing and adjusting the focal plane of separate images captured on separate sensors. The separate light beams may be differently polarized by a variable wave plate or a polarized beam splitter to allow separate manipulation of the beams for addition of more frames. These differently focused frames are then combined using image fusion techniques.
