Cheng-Jung Yang Accurate Deformable Mirror Identification for Adaptive Optics and Aberration Manipulation
Cheng-Jung Yang;Chia-Yuan Chang

Aberrations generated as the light passed through optical components and specimen. Based on the proposed identification algorithm, we constructed the first and second order aberration shape of Zernike polynomials with electrostatic membrane deformable mirror (DM). Due to the coupling effect of the DM itself, we then applied PI closed loop controller for more precisely converging to separately shape of the Zernike polynomial. The identified model can be implemented for more accurate adaptive optics correction and practical application such as auto-focusing based on aberration manipulation technique.

Ching-Yao Huang Comparison of Power Distribution in Spherical and Aspherical Tilted Prescription Lenses
Ching-Yao Huang

This study is to measure and compare the power distribution in spherical and aspherical tilted prescription spectacle lenses at different tilt angles. The results show that the effective power change along the tilt direction is less in the aspherical tilted lenses than in the spherical tilted lenses.

Cheng-Mu Tsai A Study of wide FOV Optical See-through Head-Mounted Display with Dihedral Corner Reflector Array
Jun-You Li;Cheng-Mu Tsai

An optical see-through (OST) head-mounted display (HMD) is based on a dihedral corner reflector array (DCRA) to give a wide field of view (FOV). A simulation modes combining the HMD lens, DCRA and eye model show that the eye can receive the display information in the wide FOV.

Chaohsien Chen Chromatic Aberration Variations of Conceptual Thick Lenses
Chaohsien Chen

New conceptual lens modules which can predict the variations of primary chromatic aberrations and secondary spectrum for real thick optical lenses are proposed. They are capable of studying the chromatic aberration behaviors of conceptual lenses without their detailed structures. As a comparison, they also provide accurate results than some commercial optical software.

Chia-Hui Chen Combination analysis of four common membrane stack formulas applied to dual narrow-band-pass filters
Chia-Hui Chen;Zhi-Ting Ye

This research puts forward four common membrane stack formulas and finds a relatively better membrane stack formula applied to the dual narrow-band-pass filters. We found that the Air/(LH)M L 2H L (HL)M/Sub membrane stack formula compared to the other three membrane stack formulas not only has a relatively better filtering effect on the cut-off wavelength but also at 532.5nm full width at half maximum(FWHM) of 21nm, the average transmittance is 92.97%, and 620nm FWHM 40.5nm, the average transmittance is 97.17%.

Arvind Mukundan Detection of PM2.5 and PM10 Concentration Using Hyperspectral Imaging
Arvind Mukundan;Chi -Wen Chen;Yu -Sheng Tseng;Hsiang -Chen Wang

This study proposes a method of detecting air pollution using hyperspectral imaging technology of visible light, near-infrared, and far-infrared. By assigning hyperspectral information to the images of monocular, near-infrared, and thermal imaging, principal component analysis is performed on the hyperspectral images. Beer-Lambert law and multivariate regression analysis are used to calculate the PM2.5 and PM10 concentrations which are compared with the corresponding PM2.5 and PM10 concentrations from the Taiwan Environmental Protection Agency to evaluate the accuracy of this method. This study reveals that the accuracy in the visible light band is higher than the Near-Infrared and Far-Infrared bands.
