“…The weight of the scanner is about 70 g. Two APAs are mounted on the back of the flexure support. The concept of APAs relies on the flexural-extensional principle [7][8][9]. An elastic shell bends under the extension of the piezoelectric actuation.…”

The optical scanner is one of the most important components in free-space optical communications, airborne and space-based lidars, adaptive optics, and so on. The performance of an optical scanner is frequently limited by the presence of mechanical resonances. This paper presents an analog notch filter with adjustable function to reject the mechanical resonances of the optical scanner. First of all, the structure and work principle of the piezoelectric optical scanner are introduced. Furthermore, the frequency sweep method based on virtual instruments is used to gain the natural frequency of the piezoelectric optical scanner. Then, the notch filters in series are used to reduce the oscillation of the scanner at the resonance frequencies. A variety of scanning experiments were carried out. After the introduction of the notch filter, the non-linearity was reduced to AE1.1% from AE2.1%. The linearity performance was greatly improved.

“…Because of this property, piezoelectrics have found numerous applications as transducers in sensing (Yang, 2005) and actuation (Uchino, 1997). There is a broad spectrum of industries benefiting from piezoelectrics including medical imaging (Setter, 2002), smart materials and structures (Prasad et al, 2005), and aerospace sectors (Bouchilloux et al, 2004).…”

Modeling the behavior of a radially polarized, hollow piezoelectric cylinder working at different temperature conditions is the topic of this article. The temperature dependence is taken into account through temperature-dependent material properties, pyroelectricity, and thermal dimension changes, simultaneously. The cylinder is electrically excited at its outer surface by a harmonic voltage. Two different structural boundary conditions being clamped-free and traction-free cases are considered. Symmetry of the structure, boundary conditions, and applied harmonic loads lead to an axisymmetric problem which is solved analytically. Temperature dependence of the first resonance frequency, radial stress, and displacement of the cylinder for different structural boundary conditions are then investigated. It was shown that the resonance frequency of the device is almost temperature independent in the traction-free case while it changes in the clamped-free case. The derived equations are verified by other published data and the finite-element software of Comsol Multiphysics.
