Single-Shot Phase Imaging Techniques Based on Parallel Optical Information Processing
Takanori Nomura;Naru Yoneda;Yusuke Saita

Single-shot phase imaging techniques based on parallel optical information processing are described. One is single-shot digital holography with Fresnel domain filtering using
phase modulation. Other is single-shot higher order transport of intensity phase imaging using
a computer generated hologram.

Face Recognition with a Lensfree Encrypted System
Yi-Chun Fang;Ya-Ti Chang Lee;Chung-Hao Tien

We proposed an imaging system with optical encryption. With the coded mask, the facial pattern wouldn’t reveal amid the whole process and thus keep the privacy. The intermediate images can be classified by VGG-11. Currently, with 170 training images, the system can fully recognize 43 testing images in 10 classes.

On the Study of the THz Computational Imaging
Kun-Chi Tsai;Kun‑Huang Chen;Jung-Ping Liu

Based on the scheme of optical scanning holography, we applied a tera-hertz (THz) beam modulated by a diffuser to raster scan the object target. A complex intermediate pattern is synthesized using multiple raw patterns and then be demodulated by the pre-recorded system point spread function.

Volume holographic gratings for Airy light-sheet microscope
Hung-Chuan Hsu;Sunil Vyas;Kuang-Yuh Huang;Hsien-Shun Liao;Yuan Luo

Compare to the Gaussian beam, the Airy beam provides larger FOV, higher axial resolution, and deeper penetration depth in a light-sheet microscope. Here, volume holographic grating (VHG) is fabricated for generating Airy light sheet. The present method may find important applications in designing compact illumination components for a light-sheet microscope.

An Edge-Lit Volume Holographic Optical Element for An Objective Turret in A Lensless Digital Holographic Microscope
Rong-Hao Wu-Yang;Yeh-Wei Yu;Ching-Cherng Sun;Po-Kai Hsieh;Yi-Hao Huang;Chih-Yuan Song;Tsung-Hsun Yang

This paper proposes and demonstrates the use of the edge-lit volume holographic optical element (EL-VHOE) as a reference waveguide to reduce the volume of a lensless digital holographic microscope. Additionally, a hybrid lensless Fourier transform digital holography is applied to make the EL-VHOE working as an objective turret.
