Abstract
The invention relates to an imaging system for use in operating rooms and other applications. According to one example, the imaging system includes a plurality of imaging sensors that receive image information from a subject via a plurality of spectral channels and that convert the image information into an image signal. The imaging system may include a plurality of independent imaging optics systems, such as an independent visible imaging optics system and an independent fluorescent imaging optics system, that optically couple the image information to the plurality of imaging sensors. The plurality of independent imaging optics systems corresponds to the plurality of image sensors in order to independently adjust a plurality of optical parameters, such as a size of a field of view, a position of a focal plane, and a size of an optical aperture. The imaging system may further include a plurality of motion controllers that independently control the plurality of independent imaging optics systems and a control unit that is configured to receive the image signals from the plurality of imaging sensors and to generate a plurality of image frames for transmission to a display device.
