Abstract

In high speed holography the motion of an object during the exposure causes a modulation of the interference pattern to be recorded on a hologram plate. Therefore the velocity of an object is limited. This limitation on the allowable velocity of a moving object can be relaxed by the use of a frequency chirp of the laser pulse. The applicability of this principle is examined experimentally. The result shows that limited velocity increases several times. Furthermore, employing a new arrangement similar to Michelson interferometer, a two-frequency holography is simulated for high speed objects. This arrangement is applied to a holography of a balloon breaking.
