Abstract
A stereo-imaging device that operates by translating a single lens in front of an exposed imaging sensor, or translating one of the objective lens group for higher image quality. The device and method is used as a surgical instrument guide. An objective lens with a translating lens part can directly attached in front of a camera with an exposed sensor or an endoscopic circuit with an exposed imaging fiber bundle surface to capture/record the image shift generated by the lens translation. The stereo-imaging device can realize a camera which can swing back and forth from regular 2D image capturing mode to the stereo mode to capture images for 3D viewing, or a switchable stereo endoscope without size increases of multiple imaging systems to be used for periodical 3D inspections.
