Shu-Han Chang Roll and Pitch Angular Displacement Measurement Based On Birefringence Polarization Interferometry
Shu-Han Chang, Wun-Yan Chen, Ju-Yi Lee, National Central University (Taiwan)

A roll and pitch angular displacement measurement technique is presented, which is based on the birefringence effect and phase detection of polarization interferometry with a polarization camera. The experimental results demonstrate that the maximum error is 0.041° for roll and 0.18° for pitch, and the system measurement range of 3° for both roll and pitch angles.

Chun-Yu Kao Highspeed Hyperspectral Terahertz Compressed Sensing Imaging System
Chun-Yu Kao, Chia-Ming Mai, Shang-Hua Yang, Institute of Electronic Engineering (Taiwan)

In this work, we used a commercial terahertz spectral meter and digital micromirror device (DMD) to establish a compressed sensing system. The imaging system is driven by an asynchronous optical sampling system (ASOPS). Different objects are successfully measured and reconstructed under different frequencies. The experiment result can be justified with the ground truth.

Ying-Tong Chen Comparative Analysis of Image Super-Resolution Techniques
Ying-Tong Chen, Chieh-En Lee, Chung-Hao Tien, National Yang Ming Chiao Tung University (Taiwan)

Traditional optical imaging directly records the refracted signal through a lens system. However, the image resolution is constrained by various physical limitations. Modern efforts focus on overcoming these restrictions to enhance resolution. This article will provide several methods for improving image resolution, including the implementation of post- processing techniques such as resampling and deep learning methods. A comparative analysis will reveal the most suitable method for enhancing image quality in different scenarios.

Jing-Hao Huang Realizing dynamic switchable hologram by combining liquid crystal and metasurfaces
Tsung-Yu Huang, Li-Chen Su, Jing-Hao Huang, Ming Chi University of Technology (Taiwan)

Holographic technology has attracted a great deal of interest in the fields of optics over the world owing to its potential use in future optical applications such as holographic imaging and optical data storage. In this study, we would like to achieve the full 2 phase distributions by using a metasurface with liquid crystal module under different polarization. In this method, hologram can be selected by changing the incident polarizations. Finally, we obtained the phase shifts with 4 level modulation by simulation.
