Abstract

The linear recording of a Fourier transform hologram of a 2-D object using a pseudorandom diffuser is described. The recording condition is determined by two parameters: (1) intensity ratio of the reference-to-object beam; and (2) exposure energy of the reference beam, which is estimated from the shape of the power spectrum of the diffuser and the exposure-to-amplitude transmittance curve of the recording medium. The estimating process of the recording condition is confirmed by a computer simulation and an experiment. The effect of the dynamic range of the recording medium on the reconstructed image is also discussed.
