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.

 

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.

 

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.

 

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.

 

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.

 

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.

 

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.

 

In this thesis, we tried to make ultra-thin III-V sensor by using indium phosphide epitaxial wafer by thermo-compression bonding. The device could detect signal in the light source proved by input square wave. Quantum dot could also enhance the performance of sensor.

 

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.

 

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.
