VibroMet™
500 SLDV (Scanning Laser Doppler Vibrometer)
Specifications
|
 The VibroMet™ 500 SLDV is based on a patented electro-optical configuration developed by MetroLaser. The system consists of a portable laser sensor head and electronic controller. The laser sensor head includes a laser, frequency modulator, photo-detector, color CCD camera, and two computer-controlled scanning mirrors. The electronic controller has both a demodulated velocity output and a 10.7 MHz frequency modulated signal output. The front of the controller has a signal strength indicator, two selectable velocity ranges and an array of low pass filter options. A comprehensive software package, including modal analysis, is available. The software registers the user-selected target, controls the mirrors, performs dithering if needed, collects and analyzes data, and displays 2D and 3D animations.
