Some features of the self-imaging effect in holography

Abstract

This article depicts a general case of recording a grating hologram, with the distance between the object and the hologram being arbitrarily chosen. The universality of this approach does not exclude the possibility of restoring the imaginary and real images of the grating and their self-image sequences. In the case under consideration, restoring the hologram of the grating results in the reconstruction of both imaginary and real grating images and the sequences of their self-images in ± 1st diffraction orders. An important feature of reconstructing a grating hologram is that the self-image sequences for both imaginary and real images extend to the real image area. The ratios derived in the article also show that the restoration of the grating self-image sequences occurs in the 0-th diffraction order.
