Motion picture recording and observation of light propagation using light-in-flight recording by holography and its recent advances
Takashi Kakue, Chiba University (Japan)

We introduce ultrafast motion pictures of light propagation obtained by light-in-flight recording by holography (LIF holography). LIF holography has the following advantageous features: (1) recordability of spatiotemporally continuous motion pictures of light propagation, (2) recordability of three-dimensional images of propagating light, and (3) ultrahigh temporal resolution. We also review recent advances in LIF holography.

Chang YU Lin Spectral Extraction Through a Mobile Phone with a modulated light and three-parameter sine wave fitting.
Chang YU Lin, Hsieh Hung-Chih, National United University (Taiwan)

A sinusoidal intensity modulated light source as a test signal and incident to a spectrometer. In order to separate the tested spectrum from a stray light mixed spectrum, the three-parameter sine fitting algorithm was used to calculate the amplitude intensity corresponding to the specified modulation frequency. The extracted test spectral signal was not affected by stray light. And it is developed on the mobile phone, and the separation spectrum can be obtained by using the mobile phone program.

In this paper, we show the calculation for volume holography optical element (VHOE) by VOHIL model. The phase maps visualize the phase consistency and the diffraction as well in various conditions. The model shows the accuracy of the diffraction from a volume hologram. Using VOHIL model, we visualize the diffraction property in reflection-type VHOE and make sure the limitation when designing a VHOE.

Yu-Hsin Yang, Yu-Jen Chen, National Applied Research Laboratories (Taiwan), National Taiwan University (Taiwan); Guo-Hao Lu, Chao-Feng Liu, Chi-Hung Hwang, National Applied Research Laboratories (Taiwan); Sheng-Lung Huang, National Taiwan University (Taiwan); Chun-Jen Weng, National Applied Research Laboratories (Taiwan)

This study accomplishes the auto-labeling of microscopic hyperspectral images, alleviating human involvement in labor-intensive tasks and subjective assessments. This paper outlines the methods employed for auto-labeling, encompassing noise removal through the median filter, feature extraction via the N-finder algorithm, and labeling facilitated by the spectral angle mapper algorithm. Additionally, we introduce a fully-connected neural network model for cellular classification and present preliminary findings.

Ching-Yao Huang Simulation of Effective Power Change when Wearing High-Curvature Single Tilted Lenses
Ching-Yao Huang, Da-Yeh University (Taiwan)

This study is to simulate the effective power change when wearing high-curvature single tilted prescription lenses at different single tilt angles. The results show that the more the tilted angle, the less effective power change occurring at peripheral area of the high-curvature lens, but not for the low-curvature lens. Moreover, the power change profiles are different between high-curvature and low-curvature lenses, which verifies the importance of the lens design. It is suggested that an optical system combining a spectacle lens with a model eye is more suitable for the realistic simulation of power change of tilted prescription lenses.
