Disclosed is a method for constructing a digital hologram to be displayed by of a display system. The display system includes a light modulator producing a light beam and a convergent optical device designed to make the light beam converge towards a focal point. The scene is defined by a set of luminous elements. The construction method includes a step of determining values respectively associated with the pixels of the digital hologram by summing the light contributions respectively produced by the luminous elements with weighting, for each of the light contributions, by a correction coefficient depending on the area of the intersection of a surface between the convergent optical device and the focal point, and a pencil of light having a predetermined angular opening and transmitted through the convergent optical device from the luminous element producing the light contribution concerned. An associated holographic system is also described.
A method for constructing a digital hologram representing a scene and intended to be displayed by means of a display system comprising a light modulator producing a light beam and a converging optical device designed to make the light beam converge towards a focal point, the scene being defined by a luminous elements, the method comprising:
A digital holography system comprising a construction module for constructing a digital hologram representing a scene and intended to be displayed by means of a display system comprising a light modulator producing a light beam, and a converging optical device designed to make the light beam converge towards a r, the scene being defined by luminous elements, wherein the construction module is designed to determine values respectively associated with pixels of the digital hologram by summing light contributions respectively produced by the luminous elements with weighting, for each given light contribution, by a correction coefficient depending on an area of an intersection of a surface located between the converging optical device and the focal point, and a pencil of light having a predetermined angular aperture and transmitted through the converging optical device from the luminous element producing the given light contribution.
