Abstract:
1. A medical stereoscopic endoscope for measuring a three dimensional surface of an object, comprising: a tube; two entry lenses, which are arranged spaced from each other and the fields of view of which overlap; guiding devices disposed in the tube for rotation and translation of the entry lenses relative to the tube, between a first position wherein the entry lenses are spaced apart by a distance so that that outer edges of the entry lenses protrude over the cross-sectional surface of the tube and a second position wherein the entry lenses are spaced apart by a distance so that outer edges of the entry lenses do not protrude over the cross-sectional surface of the tube; an optical displacement element that displaces the axial beam being inserted between an entry lens and the guiding devices, wherein for optical measurements, the entry lenses can be disposed at a defined variable distance from each other by means of mechanical devices integrated into the guiding devices, the entry lenses being positioned by rotating, so that the spacing between the optical axes of the entry lenses is adjustable in a defined manner by means of the devices; and an illumination device disposed in the tube for illuminating the fields of view of the entry lenses with structured light and with illuminating light to illuminate an observed structure with a pattern of the structured light and with the illuminating light, wherein the guiding devices are rotatable so that the entry lenses are positioned over the illumination device.
