A pseudodeep hologram is a thin, inclined hologram on which a one-dimensional line object is recorded by a sagittal beam system; at reconstruction, the object is read within the limits of the narrow line which corresponds to it. High angular and spectral selectivities have been obtained by these means. Attention is presently given to the possibility of recording and associative reading, in view of results from experiments in which the associative reading of a pseudodeep hologram was performed on the bases of fragments of the object in question by a simple graphic-reconstruction method. Components of images caused by the recording medium's nonlinearities are noted.
