Abstract:

A three dimensional imaging system is disclosed which includes a three dimensional display (), three-dimensional calibration equipment (), and one or more two-dimensional () or three dimensional () image scanners. The three-dimensional display () uses optical pulses (-) and a non linear optical mixer () to display a three-dimensional image (). The three-dimensional image () is generated in voxels of the display volume () as the optical mixer () sweeps the display volume (). The three-dimensional calibration equipment () uses a hologram projected proximal to a desired object () to calibrate optical imaging devices (-) and to simplify the combination of the images from one or more optical imaging devices (-) into three-dimensional information. The three-dimensional image scanner () employs optical pulses () and a non-linear optical mixer () to acquire three-dimensional images of a desired object (). The three-dimensional image scanner () captures both the shape and color of a desired object ().
