CLV-3D Compact 3-D Laser Vibrometer - Applications

The unique capabilities of the CLV-3D make it an ideal tool for numerous applications where three-dimensional information is desired from a non-contact sensor. It takes the advantages of conventional 1-D laser-Doppler vibrometers one step further to replace tri-axial accelerometers.

Piezo Motors, Loudspeakers

A piezo motor utilizes a piezo ceramics cylinder equipped with electrodes on its circumference. By applying electrical signals that are phased appropriately, the cylinder is deformed. The periodic deformation will cause a traveling wave moving the rotor and can be studied with the CLV-3D system. 3-D Vibrometers are also indispensable tools for loudspeaker design.

Automotive

In the area of brake development, engineers have long desired 3-D vibration information to more accurately characterize "squeal". With the CLV-3D this need has been addressed. For convenient, full-field 3-D measurement and visualization of operational deflection shapes, Polytec has developed the PSV-400-3D Scanning Vibrometer.

Disk Drives

The disk drive industry has achieved amazing improvements in performance while simultaneously slashing cost. Due to market pressures, the demand for increased performance at reduced cost is incessant. The CLV-3D can make comprehensive measurements for modal analysis of suspensions, E-blocks, actuator arms and HGA’s. The ability to precisely quantify the out-of-track effect of an out-of-plane mode enables disk drive engineers to achieve higher and higher tracks per inch (TPI) values. With the integration of the CLV-3D with a 3-D stage driven scan system, 3-D modal analysis of disk drive components becomes a reality that helps increase disk drive performance.
