Pulse holography of uniformly moving objects.
Holography of a uniformly moving object with a pulse laser is analyzed theoretically, and the irradiance in the reconstructed image is calculated. The image irradiance is attenuated due to object motion and due to finite path difference between the reference and the object beams. The attenuating factor due to object motion, which is the more serious one, can be calculated either in terms of a varying path difference between the reference and the object beams or in terms of a shift in object frequency due to Doppler effect. If the reference frequency is shifted so as to make it equal to the Doppler-shifted object frequency, the effect of object motion on the reconstructed irradiance can be canceled.
