CARS is a third-order nonlinear process in which molecular vibrations are coherently driven by the interference between two optical fields (pump and Stokes), and the optical field (the pump in two-pulse CARS) is anti-Stokes Raman scattered by the driven vibrations.
Drive vibrations, tape degradation, debris formation, and tape guiding all contribute to unwanted lateral tape motion (LTM), which can lead to track-misregistration errors during reading of the tape.
The cantilever is pizeoelectrically driven into vibration which is pizeoresistively sensed by Wheatstone bridge.
The solution was atomized by piezoelectrically driven mesh vibration in a small spray cap, and then millions of precisely sized droplets per second with a narrow distribution were ejected by the vibrating actuator driven at around 60 kHz.
However, the most important contributor for the BC driven BM vibration at different frequencies is still unclear.
Three different prototype beam mass systems were built and tested and all successfully displayed passive self-tuning behavior when driven by vibrations at frequencies ranging from 45 to 140 Hz and accelerations ranging from 0.007 to 2g.
The seismic signals recorded at Etna volcano during the 10 April 2011 lava fountain were analyzed to retrieve the parameters used to drive the vibration platform.
