| Research Abstract |
In this study, we propose a DHM observable in multi-view and multi-resolution. The DHM can obtain multiple reconstructed images with arbitrary resolution, depths and positions, using shifted- Fresnel diffraction, instead of Fresnel diffraction. Shifted-Fresnel diffraction based on Fresnel diffraction can calculate a reconstructed image with different sampling spacings between the hologram and the reconstructed image, as well as a shift away from the propagation axis. In addition, we used four graphics processing unit (GPU) chips in order to observe four reconstructed images in real-time from one hologram.
