Automatic Fabric Defect Detection by Compact CNN-based Machine Vision
Shao-Yu Liu;Ya-Ti Chang Lee;Chung-Hao Tien

In this study, we developed a deep learning model based on convolutional neural network (CNN) to inspect the fabric surface anomaly. Proposed compact CNN model can achieve 90% classification accuracy and defect segmentation. With advantage of fast and effective, the model has potential to be applied in real-time surface inspection.

Instantaneous Center of Rotation Online Estimation for Tracked Vehicle with Visual-Inertial Odometry
Tzu-Cheng Huang;Wen-Chuan Tseng;Jih-Liang Hsieh;Chia-Ying Chang;Shean-Jen Chen

This paper focuses on how a visual inertial odometry (VIO) fused by extended Kalman filter (EKF) estimates accurately the instantaneous center of rotation (ICR) of tracked vehicle. Employing a modified ICR-based kinematic model has resulted in better pose estimation for skid-steer movement than previous one.

Coupling Magnetic Dipole Resonance with Thin-Film Resonator to Develop Surface Enhanced Infrared Absorption Spectroscopy Techniques
Syuan-You Lin;Dao-Yang Wei;Sih-Wei Chang;Shau-Liang Chen;Hsuen- Li Chen

We show that the concept of combining thin film interference and magnetic dipole resonance to develop a surface enhanced infrared absorption (SEIRA) substrate with a large-area electric field hot zone. The substrate use optical constructive interference and magnetic dipole resonance of silicon particles to achieve strong electromagnetic enhancement effect.

The realization of Three-Dimensional Photonic Crystal Free-Standing Film based on Monocrystalline BPLC
Po-Yu Lin;Tsung-Hsien Lin

Blue phase liquid crystal is a kind of 3D photonic crystal. In this experiment, we fabricate a free standing monocrystalline BPLC film which can be designed for having the PBG across the entire visible spectrum. In addition, we can replaced different material into a BP template by the replacement technique.

Flux mapping method for improving thickness uniformity of thin films prepared by electron beam evaporation with ion assisted deposition technique
Kuan-Sheng Cheng;Chuen-Lin Tien

A flux mapping methodology for simulating film thickness distribution in E-beam evaporation with ion assisted deposition process to optimize correction mask of three mateials is presented in this paper.The thickness uniformities of the films are 0.88% for TiO2 film, 1.38% for Ta2O5 film, and 2.44% for SnO2 film, respectively.

Imprintable Thin-Film Metallic Glasses with Different Crystallinities for Surface-Enhanced Raman Scattering
Pin-Jie Chen;Chun-Hway Hsueh

Periodic nanostructures on Au-based thin-film metallic glasses with different crystallinities were fabricated in the present study for surface-enhanced Raman scattering applications. To achieve this, amorphous films were deposited using co-sputtering and thermal imprinting was adopted to emboss the as-deposited films. The imprinted films were then heat treated for different crystallinities.

Top-Gate Germanene Transistors
Bo Ying Chen;Yu Wei Chang;Si Chen Lee;Shih Yen Lin

The polycrystalline elemental 2D material germanene is formed after the post-growth annealing of amorphous germanium deposited by using the thermal evaporation on MoS2/sapphire substrates. With oxidized germanene as the passivation layer, top-gate germanene transistors are fabricated, which have revealed a possible solution of the ultra-thin 2D materials for device applications.

Design and fabrication of a null corrector for use to evaluate a 550mm diameter aspherical space mirror
Hsing-Yu Wu;Li-Chih Hu;Wei-Che Chang;Yung-Hsien Liu;Po-Hsuan Huang;Yi-Kai Huang

Upgraded the optical system from the FORMOSAT-5 satellite, the clear aperture of the 550mm aspherical primary of a Korsch telescope is regarded as a higher quality optical remote sensing satellite in the next decade. This paper addresses the development of a null corrector for use to examine the primary mirror.

Optical Properties of Deep-UV Porous AlGaN Distributed Bragg Reflectors
Yang Rong Yu;Kuo Chang Yu;Wang Cheng Jie;Lin Chia Feng

Pipe-AlGaN layers with anisotropic optical properties were formed from n+-AlGaN:Si layers. Central wavelengths of the polarized reflectance spectra were measured when the direction of the linear polarizer was perpendicular and parallel to the pipe structure and the thermal expanded property on the porous AlGaN layers.
