Abstract:
Improved fluoresced imaging (FI) and other sensor data imaging processes, devices, and systems are provided to enhance use of endoscopes with FI and visible light capabilities. A first optical device is provided for endoscopy imaging in a white light and a fluoresced light mode with an image sensor assembly including one or more image sensors. A mechanism in the first optical device to automatically adjust the focus of the first optical device wherein the automatic focus adjustment compensates for a chromatic focal difference between the white light image and the fluoresced light image caused by the dispersive or diffractive properties of the optical materials or optical design employed in the construction of the first or second optical devices, or both. Adjustment mechanisms are provided using liquid lenses or repositioning sensors. The design may be integrated with a scope or detachable.
