Paper Abstract

The pulsed laser in the picosecond and femtosecond range introduces totally new possibilities. Using light-in-flight recordings by holography the wavefront of a light beam can be studied in the form of a continuous frameless motion picture. Pulse shapes, pulse lengthening and pulse delays can be measured with high accuracy e.g. to study the quality of optical fibers and integrated optics. The light pulse also can be used as a radar pulse to measure the three-dimensional shape of industrial objects. This new technique should make possible absolute measurements down to a resolution of micrometers even when the objects are meters of size.
