	1	Terahertz quantum cascade lasers with sampled lateral gratings for single mode operation显示文摘In this paper,we presented single mode terahertz quantum cascade lasers(THz QCLs)with sampled lateral grating emitting approximately 3.4 THz.Due to strong mode selection,the implementation of sampled lateral grating on THz QCL ridges can result in stable single longitudinal mode emission with a side-mode suppression ratio larger than 20 dB.The measured peak power of the grating laser is improved by about 11.8%compared to the power of devices with uniform distributed feedback gratings.Furthermore,the far-field pattern of the presented device is uninfluenced by grating structures.

	7	Crack Length Quantification Based on Planar Eddy-Current Sensor Array and Two-Dimensional Image显示文摘Eddy-current (EC) testing is an effective electromagnetic non-destructive testing (NDT) technique.Planar eddy-current sensor arrays have several advantages such as good coherence,fast response speed,and high sensitivity,which can be used for micro-damage inspection of crucial parts in mechanical equipments and aerospace aviation.The main purpose of this research is to detect the defect in a metallic material surface and identify the length of a crack using planar eddy-current sensor arrays in different directions.The principle and characteristics of planar eddy-current sensor arrays are introduced,and a crack length quantification algorithm in different directions is investigated.A damage quantitative detection system is established based on a field programmable gate array and ARM processor.The system is utilized to inspect the micro defect in a metallic material,which is carved to micro crack with size of 7mm(length)×0.1mm(width)×1mm(depth).The experimental data show that the sensor arrays can be used for the length measurement repeatedly,and that the uncertainty of the length measurement is below ±0.2mm.
