Acoustic Camera

Visual Localization of Acoustic Emissions

The Acoustic Camera of GFaI is the first viable system to localize acoustic emissions. Brought to market in 2001 as a pioneer technique, the Acoustic Camera has become a metaphor for beamforming systems over the years. For the first time, a portable system can be used to visualize sounds and their sources. Maps of sound sources that look similar to thermographic images are created within seconds. Noise sources can be localized rapidly and analyzed according to various criteria.

Microphone arrays

For the arrangement of the microphones, we offer different array constructions for different applications.

Our wide range of standard shapes and sizes:

  • Ring Array with 32 / 48 / 72 microphones
  • Sphere Array with 48 / 80 / 120 microphones
  • Star Array with 48 microphones
  • Paddle with 48 / 104 microphones
  • Fibonacci with 120 microphones

    In addition, we can build an individual array depending on the required customization for the user.

    Data acquisition
    Data recorder mcdRec

    Data recorder mcdRec

    This data-recording device has been developed especially for use with the Acoustic Camera. It facilitates high scanning frequencies and high numbers of channels but it is lightweight and compact at the same time.

    In addition to the microphone signals, other parameters can be recorded in analog or digital format. The distinguishing feature of this data recorder is the scalability of the microphone channel number and the interface. The data recorder is equipped with a wide-range AC power supply that allows operation around the world (from 90 V to 240 V).
