Each of its pixels is sensitive to specific incident angles and supplies a component of the mathematical operation called the Fourier Transform to produce an image about 20 pixels across.
它的每一个像素点都对指定的入射角十分敏感,并提供一部分称为“傅里叶变换”的数学运算以产生一张20像素的图像。
The image obtained by PSTM depends on a various complex factors such as the sample's optical properties, the polarization of the incident field, probe properties and so on.
光子扫描隧道显微镜所得图像与很多因素有关,如:样品形貌、样品折射率、入射光的极化方式、探针的性质。
Based on ASTF the influence of such parameters as tip-sample distance, tip aperture diameter and the incident Angle of illuminating laser beam on PSTM image has been discussed.
进一步根据角谱传递函数计算了不同样品的光子扫描隧道显微镜理论图像,分析了探针与样品的间距、探针孔径大小、照明光入射角等对光子扫描隧道显微镜成像的影响。
