LMS High Definition Acoustic Camera Antenna

Features & Benefits

• Automatic measure of distance to the source

• Digital Camera with wide angle lens (640 by 880 pixels)

• SMB Microphone connectors for easy mounting/removing of the microphones

• IR sensor for distances up to 0.8m

• Flexible arm for positioning

• Special attention has been given in the design of the antenna to guarantee a dynamic range of 8 dB over the complete frequency range.

• ...and much more!

The LMS HD Acoustic Camera Antenna has been specially designed to work with the LMS Test.Lab HD Acoustic Camera software package. (see below)

The antenna contains a camera with a wide angle lens. LMS Test.Lab HD Acoustic Camera takes a picture of the source object and corrects automatically the picture for the wide angle distortion. The antenna has also an IR sensor that for user’s convenience automatically measures the distance between the antenna and the source.

LMS Test.Lab HD Acoustic Camera

Features & Benefits

• Analysis of stationary, transient or impulsive noise

• Automatic measurement of the distance when used with the LMS Acoustic Camera Antenna

• Far-field measurement to get overview of sources with resolution ≥λ. Near-field measurement with the same antenna to improve the resolution to 0.44 λ

• Capability to listen original sound or propagated

The LMS Test.Lab HD Acoustic Camera is a member of the LMS Test. Lab Acoustic Testing product family. It is a noise source identification software tool that can be used for far-field applications (beamforming) as well as near-field applications (focalization). When applying to the near-field focalization is used while for the far-field applications a beamforming technique is used.

A typical procedure to perform source localization is as follows. For a first measurement, the antenna is placed in the farfield providing a complete view of the structure. A measurement is taken and the sources are indicated on the structure with resolution equal to the wavelength or larger. If a finer resolution is needed, the antenna can be moved into the near-field, resulting in source localization with a precision of 0.44 λ.
