Measurement of the Displacement of a Shear Mode Piezoelectric Transducer Using Laser Doppler Vibrometer
This paper investigates the capability of laser Doppler vibrometer in measuring the displacement of Spectra's shear mode piezoelectric transducer. Measurements have been conducted on a fully functional 128 jets, 600 dpi commercial compact print head (CCP128/600). Displacements smaller than 0.02 μm at high jetting frequency have been successfully measured. It has been demonstrated that laser Doppler vibrometer can be effectively used to evaluate printhead dynamics, identify potential problems, verify numerical models and optimize the printhead designs.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
