Abstract
Many existing three-dimensional imaging and processing techniques are based on the explicit combination of several two-dimensional perspectives (or light stripes, etc.) through digital image processing. With holography, multiple two-dimensional perspectives are optically combined in parallel. When either of the two stages in holography, recording or reconstruction, are performed digitally the process has been referred to as computer, or digital, holography. We record digital holograms using a technique called phase-shift interferometry and introduce a third step, that of digital compression and decompression.
Keywords: digital holography, three-dimensional imaging, image compression.
