ABSTRACT
Imaging speed is one of the key factors limiting atomic force microscope's (AFM) wide applications. To improve its performance, a variable-speed scanning (VSS) method is designed in this note for an AFM. Specifically, in the VSS mode, the scanning speed is tuned online according to the feedback information to properly distribute imaging time along sample surface. Furthermore, some practical mechanism is proposed to determine the best time of moving the AFM tip to the next scanned point. The contrast experiment results show that the VSS method speeds up the imaging rate while ensuring image quality.

    Abstract. A last imaging method in a contact-mode atomic force microscope (AFM) is examined for its principle and performance, where the image is acquired by combining a cantilever signal and a feedback signal applied to a piezotube. The frequency component of the feedback signal is restricted...

    Conventional atomic force microscope nanomanipulation is inefficient because of the serial imaging/manipulation operation. We present here a parallel imaging/manipulation force microscope (PIMM) to improve manipulation efficiency. The PIMM is equipped with two individually actuated cantilevers...

    A novel algorithm is described and illustrated for high speed imaging of biopolymers and other stringlike samples using atomic force microscopy. The method uses the measurements in real-time to steer the tip of the instrument to localize the scanning area over the sample of interest. Depending...
