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…
