ABSTRACT:
A scan imaging device capable of generating a stereoscopic image of an object to be examined projects two light beams and scans the object with the light beams, and the reflected light beams are obtained through the same light path and are respectively received by two light detectors for generating a set of images with a parallax. The images are displayed alternately on a television monitor and are viewed through spectacles with polarizing screens, whereby the examiner can obtain a stereoscopic view of the object.
