GPU-accelerated calculation of computer-generated holograms for line-drawn objects

The heavy computational burden of computer-generated holograms (CGHs) has been a significant issue for three-dimensional (3D) display systems using electro-holography. Recently, fast CGH calculation methods line-drawn objects electro-holography were proposed, which are targeted holography-based augmented reality/virtual reality devices because their ability to project object contours in space with small load. However, these still face shortcomings, namely, they cannot draw arbitrary curves graphics processing unit (GPU) acceleration, is an obstacle replaying highly expressive and complex 3D images. In this paper, we propose effective algorithm calculating at layers different depths suitable implementation GPU. By combining the integral wave propagation algebraic solution, successfully calculated CGHs 1, 920 × 080 pixels within 1.1 ms on NVIDIA Geforce RTX 2080Ti
