Paper Abstract

The principle of "light-in-flight recording by holography" has been developed for studies of ultrafast phenomena. It produces a three-dimensional continuous motion picture with a resolution in the picosecond range and a time span of e.g. some nanoseconds. As the main advantage of this technique is in the study of objects with a velocity close to that of light, compensation for relativistic effects have to be made. This is true when the studied object is e.g. a wavefront of light itself, but it is also true for other high-velocity objects. It has been found that the "holo-diagram" (originally designed for holographic interferometry) is a practical device also for the evalution of relativistic effects. The relativistic rotation of wavefronts and aberration of lightrays, the Lorentz contraction and the transvers Dopplershift all can be explained by the use of this diagram. Thus the conceptual step becomes small from ordinary optics to the relativistic optics needed for the study of ultrahighspeed phenomena. Good agreement has been found between accepted relativistic equations and results from a slightly modified holo-diagram.
