Fast hologram pattern generation by radial symmetric interpolation

GPU implementation of wave field translation method for fast hologram generation

“…Thus fast holographic pattern generation is essential problem in commercialization of holographic display which is considered as ideal 3D display [1][2] [3]. In previous work of authors [4], 2 step wave field projection method was proposed to overcome accumulation problem of point source based method. In the first step, 2D projection of wave field for 3D object is calculated by radial symmetric interpolation (RSI) method [5] to the predefined reference depth, and then in step 2 it is translated toward depth direction using Fresnel transformation.…”

Application of Mathematical Symmetrical Group Theory in the Creation Process of Digital Holograms

“…Digital holograms of partial images corresponding to the set of tuples are named "partial holograms" and they are denoted by ( ) which can be obtained by (15) and the methodology of [9]. Since the transformed images to generate the corresponding holograms are linear, according to (8), the hologram corresponding to the set of tuples can be presented as follows:…”

“…In [8], only a 45-degree diagonal of the zone plates is calculated, and the first quarter of the concentric circles quadrant of the zone plates is calculated from this diagonal using interpolation and data duplicity, and using the symmetry by reflection, the zone plates are fully calculated.…”
