摘要
The viewing direction in Digital Holography can be varied if different parts of a hologram are reconstructed.In this article parallax limitations are discussed using the phase space formalism.An equation for the parallax angle is derived with this formalism from simple geometric quantities.The result is discussed in terms of pixel size and pixel number of the image sensor.Change of perspective is demonstrated experimentally by two numerical hologram reconstructions from different parts of one single digital hologram.
