Real-time volume-scanning three-dimensional imaging system for real moving objects

Abstract

A three-dimensional imaging system is described that optically dissects a real object into cross sections by illuminating it with a thin plane of light made to scan across its depth. An image-dissector camera with its axis perpendicular to the thin plane of light rapidly scans the cross sections so produced in real time. The images are displayed on a cathode-ray tube driven mechanically in an oscillatory sawtooth motion along its long axis in synchronization with the movement of the thin plane of light. A three-dimensional image containing full spatial information is produced 13 times per second.
