Acoustic Micro Imaging has been used over the past decade as a successful nondestructive technique to detect discontinuities within materials and interconnects. This paper focused on capability of this tool in detecting defect bumps by using high frequency 230 MHz MP CP4 transducer. Characterization work was done both transducer it found that acoustic image able give clearer indication than but edge effect limitation. The however clear assessment unable highlight bump clearly. Therefore...
This research addressed the drawbacks of conventional hybrid structure and processing technique by presenting a novel distributed fiber optic sensor based on Michelson Mach-Zehnder interferometer. The can achieve blind spot free positioning has wide response frequency, additionally its is not complex. It obtain two phase signals from each interferometers using demodulation method that uses 3 × optical coupler. To determine position disturbance, we computed cross-correlations following basic...
In order to lower production cost of Laser Doppler velocimeter (LDV) and simplify the system structure, a grating detection has been designed. This LDV was carried out by differential measurement mode. Two beams diffracted light from are mixed, beat frequency will be detected detector when is moving. Fundamentals also have introduced partial experiment results this given out. The result indicates experimental value agreement with theoretical value. Errors analyzed main factors affecting...
Two InAs quantum dot samples have been grown by the solid source molecular beam epitaxy (MBE) and fabricated to detectors. AlGaAs thin films inserted into region for one of two devices. The structural features studied using transmission electron microscope (TEM). photoelectric properties them measured photoluminescence (PL) photocurrent (PC) spectra. experimental results indicated that profound effects on detector. According calculations based effective mass approximation, origins peaks...
A method is introduced to measure the thin-film thickness, refractive index and other optical constants. When a beam of white light shines on surface sample film, reflected lights upper lower will interfere with each reflectivity film fluctuate wavelength. The reflection interference spectrum analyzed software according database, while thickness measured.
We report the numerical design and preliminary experiment of 2-D acoustic metamaterials composed a planar network subwavelength Helmholtz resonators. The considerably smaller size resonator to corresponding resonant wavelength, allows compact light weight for kilohertz frequency applications. Based on transmission line model describe wave propagation inside such ultrasonic metamaterials, we derived parameters as effective density compressibility. Extremely large or even negative value...
This paper designs a multifunctional remote-controllable home system based load aggregation management system. On the one hand, this combines Load Aggregators with Smart Home and presents an effective practical method to realize household management. When loads are needed adjust by aggregators, can automatically control on user side maximize utilization of energy meet demand power dispatching. other make domestic appliance remotely controlled. To functions mentioned above, consists three...
