Abstract
The volume memory is proposed to be synthesized by overlapping of 1D expanded partial holograms on the moving carrier. The collinear optical heterodyning is used for data readout. With this approach the problematic 2D spatial light modulators are not necessary. The 1D partial holograms can be recorded by both the spatial pulse integrating and the time integrating techniques. For the latter case the acousto-optical scheme with so-called double counter scanning was worked out. The experimental results on recording hand reproducing of the wideband signals in the acousto-optical scheme confirm the real possibility for creation of such a holographic memory.
