Abstract
To provide better reconstruction quality, it takes more time for
iterative algorithms, especially when multiple holograms need to be
computed. A non-iterative method for calculating a phase hologram with
adaptive weighted constraints is proposed, which iteratively
calculates the optimized phase with a rectangular aperture as the
amplitude and multiplies the initial quadratic phase as the initial
complex amplitude. Subtraction feedback is introduced to improve the
visual effect and avoid the overcompensation problem of division
feedback. The proposed method is suitable for generating non-iterative
phase holograms with different sizes, and it can further be applied to
the calculation of color holograms. It improves computational speed
under the premise of ensuring reconstruction quality and can adapt to
the needs of different systems with different sizes or different
location requirements for holographic reconstruction. Optical
experiments also demonstrate the effectiveness of this method.
