In this paper, a new hysteresis modeling method based on an improved sub-pixel blocking matching algorithm with an optimal block size and the Preisach model is proposed to model the hysteresis behavior of a nano piezoelectric actuator (PA) on nano scale in a real time system. First, the Preisach model about the hysteresis behavior of a piezoelectric actuator is introduced. Then, a real time block...
AFM has been proved to be a powerful nano-manipulation tool taking advantage of its ultra high resolution and precision. However the large spatial uncertainties associated with AFM tip positioning dual to the PZT nonlinearity and thermal drift are still challenging problems, which hinders its wide application especially in building complex structures In this paper, a probabilistic approach combined...
In this paper, the sub-pixel motion measurement for image sequences is researched, and an improved two-dimensional distance-similarity measurement based on block matching algorithm is proposed to decrease the huge computational burden of existing strategies by reducing the searching region. Then, the normal sub-pixel motion estimation based on quadratic curve fitting is analyzed and several other...
