Microscope Scanning Vibrometer

A Microscope-based Scanning Vibrometer features full-field characterization of out-of-plane motion on MEMS and microstructures employing an already exisiting optical microscope. The vibrometer hardware is connected to the microscope using the standard C-mount interface.

The System

A MSV-400 Microscope Scanning Vibrometer system consists of the optical scanning system, an OFV-551 Fiber-Optic Interferometer, the OFV-5000 Vibrometer Controller and the Data Management System (DMS), a workstation with A/D-converter, and software. A dual beam-splitter module (OFV-072) is mounted onto the microscope and the optical fiber is coupled into the optical path via the micro-scanning module (OFV-073). The latter employs an external unit to control two ultraprecise piezo-stages for scanning the laser beam through the microscope’s optics. Simultaneously a progressive scan camera (VCT-101) provides a live video stream for the DMS. The laser is moved, not the object. A steady, live video image during the whole measurement is the benefit.

Hardware and Software

The MSV Data Management System (DMS) consists of a Windows based PC in an industrial housing, hardware for scanner control, video and data acquisition, as well as the MSV-400 software suit.

The standard version PC (MSA-W-400-M2) contains an IEEE 1394 FireWire adapter, an internal signal generator board, a dual-channel D/A-converter for the scanning control and a 1 MHz-bandwidth 2-channel A/D conversion board for data acquisition. A PC-based digital demodulation with down to 1 pm displacement resolution is available as an option. A 2-channel data acquisition board as well as an external or internal signal generator with 40 MHz bandwidth are used for the high-frequency version PSV-W-400-M2-20.

The system software comes with the same outstanding features as the PSV-400 system for macroscopic scanning. Advanced Point Selection (APS) Professional software for defining scan points on the test object in any density combination and coordinate system (polar, cartesian, hexagonal or arbitrary) is a standard feature of the MSV-400 system. Up to 40,000 measurement points deliver in-depth information about the device. The results are animated directly on the video image in 3-D.

Optical Derotator

Non-contact Vibration Measurement on Rotating Objects

The Optical Derotator makes it possible in a simple way to perform non-contact vibration measurements on rotating parts with laser vibrometers. Order analysis and measurements of the operating deflection shapes at rotational speeds of up to 24,000 RPM can be realized in this way without the necessity of complex telemetry or the interference of sensor mass. The actual measurement is amazingly simple, as optics rotating at the same RPM freeze the motion of the object. This means that rotating objects, such as fan impellers for consumer products and vehicles, rotors, turbines or also tires can be measured as if at rest.

Features:

The convenient and non-contact mapping of operational deflection shapes is a specialty of Polytec’s Laser Scanning Vibrometers. Now also rotating objects such as fans for consumer products and vehicles, turbines or tires can be characterized under operational conditions up to 24,000 RPM.

The actual deflections shapes and resonant frequencies due to stiffening effects at high RPM levels are measured and can be taken into account in the validation process of FE models. By means of the Optical Derotator order analysis and vibration measurements become feasible in a simple manner. Telemetry systems become unnecessary. Sophisticated control electronics track the motion of the rotating object, resulting in a steady position of the laser beam. The actual measurement is astonishingly simple. Due to the synchronized speed of the derotator and the object appears to stand still.

The PSV-A-440 Optical Derotator is either supplied as an add-on for PSV-400 Scanning vibrometers or as a complete solution comprising the Rotating Unit with encoder input, a control unit, as adjustable base frame for angular and high adjustment, a PSV-400 Scanning Vibrometer and a single point reference laser.

  • Accurate velocity measurements indicate forward, backward and standstill conditions
  • Fast signal processing outputs 1024 measurements/second for tight process control loops needing measurement accuracy and short cycle times
  • Many interface options including ethernet, RS-232/-422, quadrature encoder and current loop
  • High performance setup and diagnostic software to configure, program and process measurements
  • User-friendly, two-line display shows velocity, length and status information on site; optional large display
  • Eye-safe, visible laser beam

Topmap Metro.Lab

Get Latest Price

TMS-100 TopMap Metro.Lab is ideally suited for measuring large-area topography on most surfaces. The large height range of 70 mm allows measurements of flatness, parallelism and step height to be made on larger objects under test with 20 nm resolution. An excellent price/performance ratio makes the Metro.Lab attractive for companies with limited budgets, lower throughput requirements or fewer measurement applications. The instrument is designed for metrology lab precision and can even replace many tactile measurements or sit side-by-side with them while not negatively impacting a budget. As is the case with all TopMap systems, the open software architecture allows routine tasks or customized user interfaces to be easily programmed.

Features:

  • Non-contact topography measuring interferometer
  • Measurement on surfaces near steep edges (e.g. drill holes) is possible due to telecentric optics
  • Handle large or small objects under test due to large 70 mm z-dynamic range
  • Fast measurement over large field-of-view
  • Enhanced 80 mm x 80 mm field-of-view using simplified stitching (optional)
