Spatial multiplexing for large-area 3D holographic recording

In this paper, we have realized a simple and efficient method to simplify the pulsed holography and holographic interferometry recording process and render such field applications feasible using low-energy laser pulses from a compact transportable system. Our method is based on masked sequential recording of small parts of the object on corresponding adjacent holographic film areas by employing a single laser pulse for each recording step. We have generated spatially multiplexed hologram consisting of a mosaic of rectangular "frames", each "frame-hologram" reconstructing a part of the object.
