The first object of this project was to develop a Second Harmonic Generation Microscopy (SHGM) using a strong pulse YAG laser. This is to apply for study of monolayers at the water surface, solution surfaces or at the transparent solid surfaces. The YAG laser and an optical zooming microscope were set on the arms of a goniometer. The incident angle of the p-polarized laser light can be adjusted to the Brewster angle of the transparent medium to avoid exposure the CCD camera of higher sensitivity to the strong reflected light. We could observe SHG images from some samples on transparent supporting medium. Beside of the development of the SHGM, we proceeded studies on the structures of Langmuir and Gibbs monolayers using vibrational spectroscopy and Atomic Force Microscopy (AFM).

本项目的第一个目标是开发一种使用强脉冲YAG激光的二次谐波发生显微镜（SHGM）。这适用于研究水表面、溶液表面或透明固体表面的单分子膜。YAG激光器和光学变焦显微镜设置在测角仪的臂上。p偏振激光的入射角可以调节到透明介质的布鲁斯特角，以避免使高灵敏度的CCD相机暴露于强反射光。在透明的支持介质上，我们可以观察到一些样品的二次谐波图像。除了SHGM的发展之外，我们还利用振动光谱和原子力显微镜（AFM）对Langmuir和Gibbs单分子膜的结构进行了研究。
