Abstract

This paper describes a new method offering relaxation of the traditional holographic restriction on the allowable velocity of a moving object, that is, that the change of path difference between the object and reference beams has to be negligible during exposure of a hologram. The proposed method depends on the frequency chirp of the laser pulse used for the hologram recording canceling the Doppler frequency shift due to the motion of the object. Experimental verification is also shown.
