摘要:
采用自组装法制备了二维六角密排的胶体晶体样品.使用直径为1.97 μm、3.35 μm、4.87 μm、7.27 μm的二氧化硅微球,对上述胶体晶体样品进行了微球成像实验,观察到微球对样品具有放大作用.用酒精半浸没微球时,通过微球观察到样品的对比度显著提高.研究结果表明:小尺寸的微球更利于接受高频信息; 微球在酒精半浸没的情况下能接受更多高频信息,因此显著提高像的对比度; 且不同频率成份参与成像,微球对这些成份的放大率是不同的.
Abstract:
Two-dimensional hexagonal close-packed colloidal crystal samples are prepared by a self-assembly method.The image properties of silica microscale spherical lenses of different diameters 1.97 μm,3.35 μm,4.87 μm and 7.27 μm are studied.We found that the microscale lens can magnify the colloidal crystal samples and the image contrast is greatly improved when the microscale lenses are semi-immersed in ethanol.Our experimental results indicate that small size lenses can receive more high-frequency Fourier components of the object and the semi-immersed microscale lenses can also efficiently intercept more high frequency components.Moreover,the magnification of the microscale lenses is different for different Fourier components of the object.
