Abstract: A modern multi-mode optical digital holographic system for experimental teaching is developed. Thesystem establishes and records frequency field of digital holograms by combining CCD technique with various optical alignments, and uses different mathematical algorithms and computing programs to realize entirely numerical reconstruction of the hologram as well as three-dimensional measurement to the reconstructed images. The principle and process of digital holographic imaging can be demonstrated in detail via the designed interface of the operation software.
