Abstract: A method for transmitting data representing a digital hologram includes: —determining raw values of a group of parameters, the raw values being determined so that a first scalar product between the hologram and a first decomposition wavelet characterized by the raw values is the maximum; —computing, for each parameter of the group, a refinement value as a function of a derivation scalar product determined on the basis of a scalar product between the hologram and a derivative of the first wavelet relative to the parameter; —determining a coefficient on the basis of a second scalar product between the hologram and a second decomposition wavelet characterized by the refinement values; and —transmitting: i) data representing the refinement values; and ii) of the coefficient.

Abstract: A method for transmitting data representative of a digital hologram represented by a set of atoms each having a diffraction spectrum in a plane of observation includes the following steps: determining an order for sets each including at least one atom, as a function of a distance, in the plane of observation, between a position of observation and a position associated to the involved set; and transmitting, for a part at least of the sets and in the determined order, descriptive data of the at least one atom included in the involved set. An associated transmission device is also described.
