Abstract

A Q-switched ruby laser, used for a light source in high-speed holography, emits light whose frequency chirps from the lower frequency side to the higher frequency side. The upper-limit speed of a moving object in high-speed holography is discussed taking this frequency chirp into consideration. Large frequency chirp rate, longer pulse width, and the introduction of an appropriate path difference between the object and reference beams permit us to increase the allowable speed of the moving object. However, the attainable speed is limited because of definite temporal overlap of the object and reference pulse beams.
