ARIES LASER VIBROMETER VELAThe optimization of vibration and acoustic characteristics is a high priority in product development labs. Thisdemand for improvement is reected in continuous development of new analysis tools and sophisticated Vibration

Measurement Technology. The Laser Doppler Vibrometer holds the current gold standard for experimental vibration

measurement and modal analysis. This product’s measurements offer critical feedback for design model validation,

manufacturing process control, inspection of nished product and preventive maintenance of in-service equipment.

VELA can be directed towards moving objects that may be difcult to access, or may be too small or too hot to

attach a physical transducer. Also, VELA takes the vibration measurement without mass-loading the target, which

is especially important for MEMS devices.

• Non-contact vibration measurement zero-mass loading

• Compact design

• Easy and simple to use

• Accurate and fast measurements regardless of surface reectivity

• High frequency vibration measurement (up to 40kHz)

• Low amplitude vibration measurement (3nm)

• Vibration characteristics analysis using time signal and frequency

response

• Natural modal analysis and operation deection shape (ODS)

analysis are available

• Frecuency Response Function (FRF) is calculated and displayed

• Various forms of scanning mesh can be generated easily

• The calculated mode shapes and the natural modes in animation

can be displayed

• Universal data output format for data exchange to other

commercial vibration analysis S/Ws.

WORkIng PRIncIPLE

ARIES Laser Vibrometer VELA is ascientific instrument used for precise

and sophisticated characterization of 

structural vibration.The laser beam from

VELA is directed at the surface of interest,

then is reflected and the frequency

of the laser is shifted proportional to

the object velocity, referred to as the

Doppler frequency shifting phenomena.

The Doppler frequency is then processed

to give output voltage proportional to

surface speed at scanned point at real

time.

• VELA-SP. Laser vibration sensor,

single point laser vibrometer.

• VELA-SD. Laser scanning

vibrometer, multipoint laser

vibrometer (surface vibration).

• VELA- S3D. Laser scanning

vibrometer 3D, measurement

and visualization of 3D vibration

characteristics.
