中日与亚洲国际原子与分子物理讨论会简史

编者按:中日原子与分子物理讨论会是由中国著名学者清泉教授与日本著名学者高柳和夫教授共同发起创办的.第一次会议于1985年8月在成都举行.第二次会议于1988年10月在日本富士山北面脚下会议中心举行.第三次会议于1990年10月在山东泰安举行.第四次会议于1992年10月在日本东京举行.此次会议又称为第一届亚洲国际原子与分子物理讨论会.从此以后,会议规模扩大了,改称为亚洲国际原子分子论坛.现将高柳和夫教授所写的会议发展简史发表在本学报.供大家参考.     

Absolute Positioning of Scanning Probe Microscope Tip by Two-Wavelength Synthetic Method

In this paper, we describe the absolute positioning of a probe tip in a scanning Wiener fringe optical microscope (SWOM) using a synthetic wavelength method. Two laser beams with different wavelengths are superimposed and are incident on a sample surface. A synthetic fringe which has a longer period than that of the Wiener fringe obtained with a single wavelength is formed on the surface. The order of Wiener fringe which is utilized as a feedback signal in the microscope can be determined by the synthetic fringe. A sample with known structure was observed for various defined fringe orders using the SWOM.
