This report describes the realization of an embedded hardware system designed to perform fast control for an atomic force microscope (AFM). Traditional implementation of control algorithms for AFMs, either PC-based or DSP-based, does not meet the high-speed scanning requirement. Considering the capability of parallel computing, FPGA is employed to achieve real-time control for an AFM equipment. Specifically, in the designed embedded system, the hardware includes several key components of signal… CONTINUE READING
