Vibrometer contain a laser , which on the surface to be measured focus is. Due to the Doppler effect shifts upon movement of the surface to be measured the frequency of the backscattered laser light. This frequency shift is in the vibrometer by means of an interferometer is evaluated and as a voltage signal or digital data stream output. A scanning vibrometer enables field measurement of vibrations. A vibrometer is generally a two beam laser interferometer that measures the frequency (or phase) difference between an internal reference beam and a test beam. The most common type of laser in an LDV is the helium-neon laser[1], although laser diodes[2], fiber lasers, and Nd:YAG lasers are also used. The test beam is directed to the target, and scattered light from the target is collected and interfered with the reference beam on a photodetector, typically aphotodiode. Most commercial vibrometers work in a heterodyne regime by adding a known frequency shift (typically 30–40 MHz) to one of the beams. This frequency shift is usually generated by a Bragg cell, or acousto-optic modulator.

Most machines work in environments where noise – levels are high. It is difficult to identify particular sounds / noise elements associated with rotational fluctuations within that ambient sound. If the machine is running with / without adequate lubrication , normal noise is disturbed and the ‘frictional noise’ can only be distinguished and measured by such sensitive instruments as the ZKL Sound Level Meter which are accurate upto 130dB. This meter is an invaluable aid on the shop – floor helping technicians and other users to measure sound levels , detect any flaws / problems and helping them to take corrective / remedial measures. Who would benefit The ZKL Sound LEVEL Meter is the instrument – of- choice for Safety Engineers , Health , Industrial Safety Offices and Quality Control Departments working in varied environments as IEC 651 Type – II, ANSI S1.4II.
