The OFV-505 sensor head integrates interferometer, laser and imaging optics in a stable. First, holographic interference using a He-Cd (325nm) laser is used to create the master of the periodic line structure on an i-line sub-micron positive photoresist film. Vibration measurement instruments and vibration analyzers are used for measuring, displaying and analyzing vibration. See more information about Polytec, Inc.

Polytec Fiber Interferometer Laser Doppler Vibrometer Electronics Unit Ofv-2802i. Cornejo-Rodriguez, E. More information about TopMap White-Light Interferometers can be found on the internet at www. ppt), PDF File (. The facilities in SSNEMS lab include CNT synthesizer, polymer processing equipment, automotive systems lab, electrospinning pump and high voltage DC source, data acquisition boards and DSP processors, rectilinear ECP plant, vibration testing rig, actuators (electromagnetic shakers, piezoelectric bimorph and stack actuators), and sensors (laser sensors, optical encoders, PVDF sensors, strain. Polytec's fibro vibrometers are very successful. As object movement away from the interferometer generates the same modulation pattern (and modulation frequencies) as object movement towards the interferometer, this set-up alone cannot unambiguously determine the direction the object is moving in. A displacement DL(t) = λ/2 causes the phase change f(t) = 2π. Generally, in MEMS devices, elements for sensing and actuation are actively moved. They determine vibrational velocity and displacement from the Doppler shift of back-scattered laser light. A laser vibrometer is built with a modified Michelson interferometer using polarized light. One of the two laser beams is called the reference and the other the measurement beam. Mit mehr als 400 Mitarbeitern weltweit entwickeln, produzieren und vertreiben wir optische Messtechnik-Lösungen für Forschung und Industrie. de Polytec GmbH. For more than 40 years Polytec‘s optical Sensors enable industry and research to measure vibration, length, velocity, topography as well as spectral properties of materials. The Hydro-method is designed to be faster, more economical, and more precise than the current means of measuring roping. Abstract: An optical interferometer including an output-beam beam input for coupling-in an output beam, and a beam splitter device for splitting the output beam into at least one first sub-beam and one second sub-beam, the interferometer being embodied as a heterodyne interferometer by virtue of at least one optical frequency shifter being. Where to Buy White Light Interferometers. Equipment that measures speed and movement using a Doppler interferometer. The laser beam from the LDV is directed at the surface of interest, and the vibration amplitude and frequency are extracted from the Doppler shift of the reflected laser beam frequency due to the motion of the surface. A common interferometer is the white-light scanning interferometer or the coherence scanning interferometer [24–29]. Designed to be quick, easy to operate and free from cross-talk or feedback problems, these instruments determine a structure's. com Modular Vibrometer System OFV-5000 Vibrometer Controller - Velocity Decoders - Displacement Decoders OFV-505/503 Standard Sensor Heads OFV-551/552 Fiber Interferometers OFV-534 Compact Sensor Head High Performance Vibration Measurement. Incorporating a scanning white light interferometer, the Metro. high precision white light interferometer for on line part inspection and product and quality control. Laser Doppler vibrometers (LDVs) measure vibrations where other sensors can't. The Polytech MSA-500 Micro System Analyser (called the "Vibrometer") is a fully-integrated  Structural Dynamics and Surface Metrology System. de Polytec France S. At the heart of every Polytec vibrometer system is the laser-Doppler vibrometer – a precision optical transducer used for determining vibration velocity and displacement at a fixed point. Changing setting does not affect the signal. The surfaces to be examined are often situated in areas that are difficult to inspect using most methods - an easy task for Polytec's scanning white light systems in contrast [] to the difficulty associated with contact profilometr y o r optical c o here n t interferometry. Designed to be quick, easy to operate and free from cross-talk or feedback problems, these instruments determine a structure's velocity and displacement from the Doppler shift of back-scattered laser light. Data acquisition is achieved by a fiber - optic laser interferometer (Polytec OFV 1000) that measures the voltage proportional to the transverse velocity of any desired point on the surface.
