Method and device for reconstructing a digital hologram, method for displaying a digital hologram and associated system

摘要

A digital hologram is represented by a set of coefficients (cθ,ξ,x,y) respectively associated with a plurality of definition wavelets each defined by a multiplet of coordinates (θ,ξ,x,y) in a multidimensional space. A method for reconstructing the digital hologram with a view to its display by means of a display (202), comprises the following steps: - as a function of at least one datum (C; P) representative of a characteristic of the display (202), determining a transformation of said multidimensional space;- generating a reconstructed hologram by assigning each coefficient among at least some of said coefficients (cθ,ξ,x,y) to a reconstruction wavelet defined by a multiplet image reconstruction by the determined transformation of the multiplet of coordinates defining the wavelet of definition associated with the coefficient concerned (cθ,ξ,x,y). A related display method, reconstruction device and system are also disclosed. Figure for abstract: 1
