on how the laser Doppler vibrometer (also generally abbreviated to LDV) has reached its current state . 500 Hz, 0.75 Hz resolution, 30 averages per point, measurement time 8 hours). a) b) media used in magnetic hard disk drives.
29 Oct 2014 Time-resolved fuel injector flow characterisation based on 3D laser . duration is sufficiently long, as can be the case for medium and high engine load [28]. The laser Doppler vibrometer [29] was a Polytec PSV-400-3D
Dynamic & High-Resolution. LV-1800. Vibrometer using the non-contact Laser Doppler Method. Small and light-weight sensor with excellent ease of use
requirements for laser Doppler vibrometers (LDVs) have continuously grown to confront the demands of increased resolution, bandwidth and accuracy. In this.
Our digital Laser Doppler Vibrometer achieve the following excellent performance features: Extremely fine resolutions of up to 2.5 nm/s (velocity) and 2 pm
The Laser-Doppler vibrometer works on the basis of optical interference, Using suitable interpolation techniques, Polytec's vibrometers attain a resolution of 2
13 Aug 2013 Laser Doppler Vibrometry (LDV) has been widely used in (using displacement decoding) down to sub-picometer resolution per vHz [1, 2]. .. ultrasonic methods would require contact and a coupling medium, which could
Digital Laser Doppler vibrometers (LDV) are very fast and easy-to-operate vibration signal processing provides precise, high-resolution data enormously fast.
