| 1 | Microstructures of brazing zone between titanium alloy and stainless steel using various filler metals显示文摘Titanium alloy (Ti-Al-V alloy) substrate was brazed with stainless steel (STS304) using filler metal.At an optimized brazing condition,various filler metals were used.Microstructures were observed at each condition.Filler metals were titanium based 40Ti-20Zr-20Cu-20Ni,silver based Ag 5Pd,and nickel based Ni-7Cr-3.1B-4.5Si-3Fe-0.06C (BNi2) and Ni-14Cr-10P-0.06C (BNi7).To select a good filler metal for brazing process,wetting test was performed at 880-1050 °C.It was not brazed using silver based filler metals,but at the conditions using titanium and nickel based filler metals had brazed zone between titanium alloy and stainless steel.However,titanium alloy was eroded during brazing using titanium based filler metals.Nickel based filler metal has a good brazed zone between titanium alloy and stainless steel among the filler metals. | Taeshin CHUNG Jungsoo KIM Jeongseok BANG Byoungho RHEE Daegeun NAM | 2012 | 中国有色金属学会会刊:英文版2012，22，S3： | 12 |
| 2 | Spatial phase-shifting interferometry with compensation of geometric errors based on genetic algorithm(Invited Paper)显示文摘We propose a novel spatial phase-shifting interferometry that exploits a genetic algorithm to compensate for geometric errors. Spatial phase-shifting interferometry is more suitable for measuring objects with properties that change rapidly in time than the temporal phase-shifting interferometry. However, it is more susceptible to the geometric errors since the positions at which interferograms are collected are different. In this letter, we propose a spatial phase-shifting interferometry with separate paths for object and reference waves. Also, the object wave estimate is parameterized in terms of geometric errors, and the error is compensated by using a genetic algorithm. | Joonku Hahn Hwi Kim Yongjun Lim Eun-Hee Kim Byoungho Lee | 2009 | Chinese Optics Letters2009，7，12： | 2 |

| 7 | Acceleration method for computer generated spherical hologram calculation of real objects using graphics processing unit(Invited Paper)显示文摘Graphics processing unit(GPU)based fast calculation method for computer generated spherical hologram(CGSH)of a real-existing object is proposed.Three-dimensional(3D)point cloud is constructed by capturing a real-existing object from multiple directions using a depth camera.The GPU based calculation is used in both hologram generation part and numerical reconstruction part of the CGSH.The improved calculation efficiency is verified by comparing the computation speed between central processing unit(CPU)based and GPU based implementation. | Gang Li Keehoon Hong Jiwoon Yeom Ni Chen Jae-Hyeung Park Nam Kim Byoungho Lee | 2014 | Chinese Optics Letters2014，12，6： | 1 |
