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…
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…
Random phase-free computer-generated hologram
Tomoyoshi Shimobaba, Tomoyoshi Ito
Addition of random phase to the object light is required in computer-generated holograms (CGHs) to widely diffuse the object light and to avoid its concentration on the CGH; howeve…
Handheld and low-cost digital holographic microscopy
Atsushi Shiraki, Yusuke Taniguchi, Tomoyoshi Shimobaba +2
This study developed handheld and low-cost digital holographic microscopy (DHM) by adopting an in-line type hologram, a webcam, a high power RGB light emitting diode (LED), and a p…
