ABSTRACT:
A stereo endoscope including a pair of objective optical systems, a pair of relay optical systems, an imagery optical system having a single optical axis, and a pair of imaging devices. The imagery optical system is a zoom optical system or a varifocal optical system. For example, an encoder is used to detect a magnitude of moving lenses in the zoom optical system. Based on the detected magnitude, a control unit allows the two imaging devices to approach or depart from each other. Thus, the stereo endoscope attains the coincidence between observation points of right and left fields of view against the displacement points of right and left object images resulting from variations of zooming magnifications.
