Journal ArticleDOI
TL;DR: An advanced coded imaging is proposed which makes it possible to clear away the side lobes from reconstructed images by using a pair of coherent codes.

TL;DR: In this article, the edge effect in thermoplastic-photoconductor media has been studied and it was found that edge effect is in proportion to both the light intensity and the spatial frequency of the holograms, and is more remarkable in the PLA method than the conventional simultaneous method.
Abstract: An edge effect in thermoplastic-photoconductor media has been studied and it is found that the edge effect is in proportion to both the light intensity and the spatial frequency of the (holograms, and is more remarkable in the PLA method than the conventional simultaneous method. These results suggest that the edge effect is caused by the electric field which is bent by the uneven surface charges, the trapped charges and the localized charges in the photoconductor medium.

Journal ArticleDOI
TL;DR: In this paper, the authors studied the error in measuring displacements of an object by speckle interferometry and showed that cameras with focal plane shutters displace to some extent, regardless of ways of mounting.

TL;DR: The behavior of the charge carriers in the thermoplastic-photoconductor system has been studied by the measurement of the diffraction efficiency instead of the usual current measurement, and the followings are found.
Abstract: The behavior of the charge carriers in the thermoplastic-photoconductor system has been studied by the measurement of the diffraction efficiency instead of the usual current measurement, and the followings are found. (1) The charge carriers are injected from the transparent conductor to the photoconductor and the minus charge injection depth is estimated to 0.1 mu m for 1:10 TNF:PVK complex and 0.3 mu m for 4:10 TNF:PVK complex. (2) A kind of rectification effect is analogous to that of the p-type semiconductor-metal system exists at the photoconductor transparent conductor interface.

TL;DR: In this article, the feasibility of applying temporal reference holography to detection of moving acoustic radiation sources is examined theoretically and experimentally, and it is proved that the point spread functions coincide with amplitude spectra of sound waves used for recording them.
