Effect of non-uniform illumination on performance of solar thermoelectric generators

Ershuai YIN, Qiang LI, Yimin XUAN

Frontiers in Energy 2018, Volume 12, Issue 2,   Pages 239-248 doi: 10.1007/s11708-018-0533-7

Abstract: The two-dimensional Gaussian distribution is employed to modify the illumination profiles incident onSix non-uniformities of solar illumination are investigated while keeping the total energy constant.The influences of non-uniform illumination on the temperature distribution, the voltage distribution,The result shows that the non-uniformity of the solar illumination has a great effect on the temperatureReducing the number of the thermoelectric legs for non-uniform solar illumination can greatly increase

Improvement in Resolution of Multiphoton Scanning Structured Illumination Microscopy via Harmonics

Lei Wang,Xiaomin Zheng,Jie Zhou,Meiting Wang,Jiajie Chen,Youjun Zeng,Gaixia Xu,Ying Wang,Haixia Qiu,Yonghong Shao,Junle Qu,Bruce Zhi Gao,Ying Gu,

Engineering 2022, Volume 16, Issue 9,   Pages 65-72 doi: 10.1016/j.eng.2021.12.010

Abstract:

We describe a multiphoton (mP)-structured illumination microscopy (SIM) technique, which demonstratesThis nonlinear response is caused by the effect of nonsinusoidal structured illumination created by scanninga sinusoidally modulated illumination to excite an mP fluorescence signal.The harmonics of the structured fluorescence illumination are utilised to improve resolution.
