A large scan area high-speed scan stage for atomic force microscopy using the resonant oscillation of a quartz bar has been constructed. The sample scanner can be used for high-speed imaging in both air and liquid environments. The well-defined time-position response of the scan stage due to the use of resonance allows highly linearized images to be obtained with a scan size up to 37.5 mum in 0.7 s. The scanner is demonstrated for imaging highly topographic silicon test samples and a semicrystalline polymer undergoing crystallization in air, while images of a polymer and a living bacteria, S. aureus, are obtained in liquid.
已构建了一种用于原子力显微镜的大扫描区域高速扫描台,该扫描台利用石英棒的共振振荡。样品扫描仪可用于在空气和液体环境中进行高速成像。由于使用共振,扫描台具有明确的时间-位置响应,这使得在0.7秒内扫描尺寸高达37.5μm时能够获得高度线性化的图像。该扫描仪已用于对高形貌硅测试样品以及在空气中结晶的半结晶聚合物进行成像,同时在液体中获得了聚合物和活细菌金黄色葡萄球菌的图像。
