摘要：

This payer describes the experimental realization of a recently proposed scanning reference beam technique for hologram transmission. The apparatus uses an extremely simple method for obtaining the two different but phase‐locked optical frequencies necessary for the heterodyne mode of operation. The paper shows reconstructions obtained from transmitted holograms of two‐ and three‐dimensional objects, analyzes the signal‐to‐noise ratio and resolution attainable with this technique, derives a new general theorem concerning the detectability of the interference between two arbitrary beams, and discusses the theorem's applications to this system. © 1969 The Bell System Technical Journal
