A laser Doppler vibrometer (LDV) is a non-contact instrument for measuring vibration. Doppler effect - Wikipedia The scanning laser vibrometer or scanning laser Doppler vibrometer, was first developed by the British loudspeaker company, Celestion, around 1979, further developed in the 1980s, and commercially introduced by Ometron, Ltd around 1986. The laser Doppler vibrometer (LDV) system used for calibrating the spring constant of AFM cantilevers is housed 12 m underground in the Nanomechanical Properties Group’s clean room lab in the Advanced Measurement Laboratory (AML) at NIST. The lab affords a clean, low vibration environment with good temperature and humidity control.

Laser doppler vibrometer

Laser scanning vibrometry-Wikipedia A Laser Doppler Vibrometer (LDV) is a scientific instrument that is used to make non-contact vibration measurements of a surface. The laser beam from the LDV is directed at the surface of interest, and the vibration amplitude along with frequency are extracted from the Doppler shift of the reflected laser beam frequency due to the motion of the surface. The laser-Doppler vibrometer (LDV) is a research tool that can be used to quickly measure the sound-induced velocity of the tympanic membrane near the umbo (the inferior tip of the malleus) in live human subjects and patients. In this manuscript we demonstrate the LDV to be a sensitive and selective … laser doppler vibrometer Bids, RFPs & Government Contracts. InstantMarkets provide easy interface to find business opportunities accross globe including bids, contracts, awards, solicitations, RFPs, RFIs, RFQs and other opportunities from all government agencies and private companies 2019-08-31 This research focuses on mounting Laser Doppler Vibrometer (LDV) on an Unmanned Aerial System (UAS) to enable contact-free transverse dynamic displacement of railroad bridges. Researchers conducted three field tests by flying the Unmanned Aerial Systems Laser Doppler Vibrometer (UAS-LDV) 1.5 m away from the ground and measured the displacement of a moving target at various distances.
