CLV Compact Laser Vibrometer The Compact Laser Vibro-meter is a non-contact transducer for vibration measurements in production lines and research and development (R&D) applica-tions. Polytec fiber vibrometers are selected when test surfaces are hard to reach, stand-off distances are relatively short or the smallest measurement spot is necessary. Lab is an affordable, high-precision, non-contact topography measurement system designed to characterize flat and curved surfaces. The LTCC wafer and a silicon wafer with diaphragms were anodically bonded in vacuum, and then the deformation of the diaphragms in air was measured by white light interferometry using Polytec’s. com Fb16 elektrotechnik informatik confocal linnik white light fundamental aspects of resolution and precision in vertical scanning fundamental aspects of resolution and precision in vertical scanning zygo white light interferometer images of a 12 5 l m radius recessed. GREMAN is a research laboratory on materials, microelectronics, acoustics and nanotechnology of the university of Tours, CNRS and INSA Centre Val de Loire. 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. Evidence of this has been confirmed and stored by OTRS volunteers, under ticket number 2012062010006379. Despite the small size, the sensor head is a high performance vibrometer with video camera (OFV-A-534-CAM/CAP camera option) for online monitoring of the measurement. The vibrometer consists of the con-troller OFV-3001 and the sensor head OFV-303/-353 or OFV-511/-512. The following is a description of the created measurement application, divided into three parts: decoding an S/PDIF, acquisition and display of digital data and acquisition and display of analog data to compare with digital output. This is a file from the Wikimedia Commons. Information from its description page there is shown below. 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. fr Polytec Ltd. Lab is an affordable, high-precision, non. Line is the ideal production control system for precisely measuring surfaces as they are manufactured. Fiber Optic Interferometer -- OFV-551 Fiber-Optic Interferometer -- OFV-552: Polytec Laser Doppler Vibrometers are precision tools for non-contact vibration measurement. There is no need of the costly process of establishing all the. Description: Polytec Laser Doppler Vibrometers are precision tools for non-contact vibration measurement. 05 - 2 MHz frequency range controller from Polytec PI, Inc. Louis 35 Fabry-Perot interferometer for non-contacting detection of ultrasonic vibrations in the 2 - 50 MHz frequency range from UltraOptec, Inc. 20ppm for the phase refractive index and 0. The instrumentation diagram of the acoustic excitation and interferometric detection. Polytec's white-light interferometers are suited to use in a metrology chamber, located near the production line or installed directly in-line. Contact info for the new office is as follows: Polytec 25 South Street, Suite A Hopkinton, MA 01748. 01 Ångstroms for its best systems, which are called vibrometers. With this. Responsible for manufacturing processes and test equipment. Researchers of the Berkeley Sensor & Actuator Center have general access to three TESTING TOOLS FOR DYNAMICS in MEMS: A Stroboscopic Interferometer System (developed at BSAC) to measure out-of-plane motions and deflections (SMIS). Generally, in MEMS devices, elements for sensing and actuation are actively moved. Erfahren Sie mehr darüber, wie es ist, bei Polytec, Inc. The frequency-shifter in the heterodyne interferometer is a slow-shear-mode Bragg cell. Column "To": S = list of suppliers for that product, E = encyclopedia article. The Magnetostriction Measurement Setup Using Dual Heterodyne Laser Interferometers In the new setup, two heterodyne laser interferometers (Polytec Industrial Vibration Sensor IVS200; calibrated for 5 mm/s/V) are placed opposite to each other with the SST in between. The heterodyne two-beam interferometer has been proven to be the optimal solution for laser-Doppler vibrometry regarding accuracy and signal robustness. The system consists of a heterodyne interferometer with a controller box. 98 Heterodyne laser interferometer setup 99 In the laser setup two heterodyne laser interferometers (Polytec IVS 200), each calibrated for 5 100 mm/s/V are used. Using a low coherence source, interference is only observed when the path length is.
