Efficient Digital Holographic Image Reconstruction on Mobile Devices

Advanced digital holography attracts a lot of attentions for 3D visualization nowadays. The representation of digital holographic images suffers from computational inefficiency on the mobile devices due to the limited hardware for digital holographic processing. In this paper, we point out that the above critical issue deteriorates the digital holographic image representation on the mobile devices. To reduce computational complexity in digital holographic image reconstruction, we propose an efficient and effective algorithm to simplify Fresnel transforms for the mobile devices. Our algorithm outperforms previous approaches in not only smaller running time but also the better quality of the digital holographic image representation for the mobile devices.
