Non-Contact Vibration Sensors
Technology From: Polytec
Single-Point Vibrometers
Single-point vibrometers measure the amount of vibration at a single point on an object's surface. More specifically, a laser vibrometer measures the projected component of an object's surface vibration vector along the direction of the incident laser beam. For example, if aligned perpendicularly to surface under test, the vibrometer measures the out-of-plane vibration to the surface (the instrument is sometimes referred to as an out-of-plane vibrometer).

Scanning Vibrometers
Polytec scanning vibrometers make vibration measurement and analysis simple and efficient.
Tell us about your structural vibration measurement task and we'll provide the scanning vibrometer solution for frequencies from DC up to 24 MHz and vibrational velocities of 0.02µm/s up to 20m/s.
As your requirements expand, you can upgrade and enhance your vibrometer step by step. Choose between 1-D (out-of-plane) systems, e.g. for sound radiation measurements, or 3-D vibrometers (complete vibration vector) which provide a three-dimensional data set for conducting modal analysis. For microstructures, we recommend our Micro System Analyser (MSA).

Non-Contact Speed & Length Control
Technology From: Polytec
Measuring Speed and Length with a Non-Contact LSV
Laser Surface Velocimeters (LSV) measure speed and length of moving surfaces accurately and without contact on coils, strips, tubes, fibre, film, paper, foil, composite lumber and almost any other moving material, including hot steel. These LSV systems are designed to perform continuously in harsh environments. The LSV control processor is easily interfaced with your process through its digital or analogue interfaces.
Advantages of using a LSV over a Wheel for Measuring
- LSV is not contact
- More accuracy
- Excellent repeatability and reduced product waste
- No scratching or surface damage
- No slippage, chatter or changing wheel diameter
- Significantly reduced maintenance
- No recalibration
- Fast and Simple Integration
- No interference to surface material, like flexing or stretching
LSV-1000 — Measuring Speed & Length of Continuous Goods
The compact LSV-1000 velocimeter measures non-contact length and speed measurement of continuous goods. The LSV-1000 is fast, precise and reliable for accurate control of cut-to-length applications. Optimised for the core tasks, the system offers rapid ROI to the user.
LSV-2000 — Measuring Speed & Length, Standstill and Direction Detection
The LSV-2000 is fast, reliable and measures forward, backward and standstill. It fits perfect into any application for process control i.e. in Cut-to-Length applications. The excellent performance and cost effective design results in a fast return on investment to the user.
LSV-300 — Measures Forwards, Backwards and Standstill
The robust, IP 66 protected LSV Controller powers the sensor head and provides signal conditioning and processing. It accepts commands from process controllers and can be monitored by a computer via its serial interface. The LSV controller easily integrates with a local area network (LAN) through the optional Ethernet interface. Length and velocity data are simultaneously displayed and updated every millisecond at each output.
LSV-6000 — Highly Accurate Speed & Length Measurements in Mill Environments
Without compromising important features such as accuracy, velocity direction (+/-) or zero speed measurement (stand still detection), Polytec designed and built a rugged and reliable instrument for velocity and length measurements in difficult mill environments. By incorporating advanced laser technology, the LSV-6000 Series eliminates common problems that plague traditional contact-wheel measurement methods such as slippage, chatter, changing wheel diameter and frequent maintenance.

MEMS Dynamics & Topography
Technology From: Polytec
Topography (White Light Interferometry)
Polytec is addressing the surface metrology market with innovative, high-precision 3-D profilometer technology that works on rough, smooth and stepped surfaces without contact. These products are based on scanning white-light interferometry, also called coherent or vertical scanning interferometry or coherence radar. With their large vertical range and nanometre resolution, they are ideal tools for determining flatness, height differences and parallelism of large surfaces and structures, including soft materials.

Surface Metrology
Hard disk drives are manufactured with nanometre precision. The slightest change in manufacturing can cause surface roughness variations large enough to cause failures in the field. For the best yields it is necessary to optimise your process. Measuring and understanding the characteristics of your product allows continuous improvement.
The AVT-1000 Advanced Vibrometry Tester enables you to measure all critical parameters such as roughness, waviness, and defects across the whole surface of the sample providing important information for process optimisation. No other technique can give you such precise, quick, and full surface measurement results.

SAW & RF MEMS Analysers
The UHF-120 Vibrometer can characterise the out-of-plane vibrations at ultra-high frequencies, extending the vibration frequency bandwidth up to 1.2GHz. Complete with a new optical design, the instrument retains the advantages and features familiar to laser vibrometer users.
The system consists of a heterodyne interferometer with a controller box. The optical head provides a heterodyne detector signal that is acquired with a fast digital oscilloscope. The digitized detector signal is transferred to a PC where the heterodyne carrier is demodulated by a new software module in Polytec's Vibsoft package.

Technology From: Polytec
Dynamic Stress & Strain Measurements
Understanding the origin of the stress and strain distribution is crucial to increasing the durability of components under dynamic load. Numerical simulations based on finite element (FE) models help with this understanding but must be validated by real component data. Polytec's 3-D Scanning Laser-Doppler Vibrometer with StrainProcessor provides an advanced, non-contact optical test solution.
Polytec's StrainProcessor is a measurement extension developed for easy FE
The Scanning Vibrometer makes a series of non-contact deflection measurements on a predefined grid using the laser probe to characterise strain at each point instead of attaching individual strain gauges. Thus, the test set-up is fast and very repeatable with no mass loading from an attached transducer. Tests are fast and avoid the high cost of preparing and instrumenting the sample with strain gauges.
