ABSTRACT:
An apparatus for optically observing a wavefront from an object on real-time basis to determine an optical characteristic of the object and observing two-dimensional images at positions taken in the direction of the depth of a three-dimensional object, that is, equidistant images on real-time basis, using four-wave mixing technique.
