Improvement of the image quality of random phase--free holography using an iterative method
Tomoyoshi Shimobaba, Takashi Kakue, Yutaka Endo +8
Our proposed method of random phase-free holography using virtual convergence light can obtain large reconstructed images exceeding the size of the hologram, without the assistance…
Random phase-free kinoform for large objects
Tomoyoshi Shimobaba, Takashi Kakue, Yutaka Endo +7
We propose a random phase-free kinoform for large objects. When not using the random phase in kinoform calculation, the reconstructed images from the kinoform are heavy degraded, l…
Optical encryption for large-sized images using random phase-free method
Tomoyoshi Shimobaba, Takashi Kakue, Yutaka Endo +7
We propose an optical encryption framework that can encrypt and decrypt large-sized images beyond the size of the encrypted image using our two methods: random phase-free method an…
Numerical investigation of lensless zoomable holographic multiple projections to tilted planes
Tomoyoshi Shimobaba, Michal Makowski, Takashi Kakue +7
This paper numerically investigates the feasibility of lensless zoomable holographic multiple projections to tilted planes. We have already developed lensless zoomable holographic…
Ptychography by changing the area of probe light and scaled ptychography
Tomoyoshi Shimobaba, Takashi Kakue, Naohisa Okada +4
Ptychography is a promising phase retrieval technique for visible light, X-ray and electron beams. Conventional ptychography reconstructs the amplitude and phase of an object light…
