| 1 | The theory and experiment of very-long-wavelength 256×1 GaAs/Al_(x)Ga_(1-x)As quantum well infrared detector linear arrays显示文摘The 256×1 linear array of multiple quantum wells infrared photodetector (QWIP) is designed and fabricated for the peak response wavelength at λP=14.6 μm. The response spectral width is bigger than 2.2 μm. The two-dimensional (2D) diffractive coupling grating has been formed on the top QWIP photosensitive pixel for coupling the infrared radiation to the infrared detective layers. The performance of the device at VB=3 V and T=45 K has the responsibility 4.28×10-2 (A/W), the blackbody detectivity Db*=5.14×109 (cm·Hz1/2/W), and the peak detectivity Dλ*=4.24× 1010 (cm·Hz1/2/W). The sensor pixels are connected with CMOS read out circuit (ROC) hybridization by indium bumps. When integral time is 100 μs, the linear array has the effective pixel of QWIP FPA Nef of 99.2%, the average responsibility (V/W) of 3.48×106 (V/W), the average peak detectivity Dλ* of 8.29×109 (cm·Hz1/2/W), and the non-uniformity UR of 5.83%. This device is ready for the thermal image application. | GUO FangMin LI Ning XIONG DaYuan ZHEN HongLou XU XiangYan HOU Ying DING RuiJun LU Wei HUANG Qi ZHOU JunMing | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，7： | 1 |
| 2 | Attitude control of apricot during orientation transmission显示文摘The kinetic characteristics of apricots during orientation transmission were studied to provide a basis for improving the structure of the transmission device.Previous studies have generally focused on the development of orientation devices,but few studies have been conducted to analyze the mechanisms of orientation.In order to study the attitude control in the orientation mechanisms,an orthogonal combination test was performed and a rigid kinetic model for a monosymmetric apricot was developed based on Euler’s kinetic equations with the modified Rodrigue parameters(MRPs).Kinetic simulation and analysis based upon the attitude control law were conducted and an attitude control simulation platform was created.The simulation results showed that the orientation transmission system for monosymmetric apricots was globally convergent and tended to stable.The experimental torques also affected the orientation success rates.The calculated average experimental torque value(0.164 N·m)was consistent with the maximum control torque value(0.16478 N·m)when the system was in a stable state in Simulink.The consistency between the simulation result and the calculated control torque validates the correctness of the designed control torques. | Ding Xiangyan Wang Chunyao Huang Chunyang Luo Jianqing | 2016 | International Journal of Agricultural and Biological Engineering2016，9，5： | 1 |
