Application

Transducer Characterization

Full broadband beam profiles in a single scan — 0 to 5 MHz at 0.1 mm resolution. No couplant, no water tank, no repeat scans at different frequencies.

Interactive transducer scan report — 1.5 MHz transducer at 0.1 mm resolution

Why BROADSONIC Characterization

One Scan Replaces Dozens

A single BROADSONIC scan captures the complete 0–5 MHz spectrum at every spatial point. Conventional approaches require separate scans at each frequency of interest.

0–5 MHz Bandwidth

Full broadband spectrum captured at every pixel in a single pass. No frequency pre-selection required.

0.1 mm Resolution

100 μm spatial resolution from a single-point optical sensor. Resolve fine beam structure that larger sensors blur out.

Minutes per cm²

Fast enough for production QA, not just one-off lab measurements. Results delivered within one week.

Non-Contact

No couplant, no water tank, no loading effects on the transducer under test. Measures the actual radiated acoustic field in air.

What You Get

Spatial Vibration Maps

2D amplitude maps at any frequency of interest across the 0–5 MHz band. Each scan pixel contains a full frequency spectrum, so maps can be reconstructed at any frequency in post-processing. No need to decide on frequencies before scanning.

Interactive Reports — No Software Required

Results are delivered as a browser-based interactive HTML report that opens in any browser with zero software installation. Unlike proprietary analysis tools that lock data behind expensive licenses, our reports are fully self-contained and shareable.

  • Spatial amplitude maps at any user-selected frequency across the 0–5 MHz band, with a frequency slider for real-time exploration
  • Per-pixel spectrum viewer: click any point on the spatial map to see its full frequency spectrum
  • Color scale controls for adjusting dynamic range and visualization
  • Exportable raw data in standard formats for further analysis in your own tools

Share reports with colleagues, customers, and regulators — anyone with a browser can explore the data themselves.

Scanning a Transducer Beam Profile

A BROADSONIC sensor mounted on a precision translation stage scans the acoustic field of an ultrasonic transducer point-by-point. The full 0–5 MHz spectrum is captured at every position in a single pass.

Why This Application Exists

Conventional transducer characterization methods face fundamental limitations that BROADSONIC eliminates.

Hydrophone Scanning

Requires water immersion, couplant, and careful alignment. Critically, hydrophone scans are typically performed at a single frequency per pass — characterizing a transducer across its full bandwidth requires many separate scans. BROADSONIC captures the full 0–5 MHz bandwidth in a single pass.

Laser Vibrometry

Can achieve high resolution but requires direct optical access to the transducer face, costs $100K+ for the system, and measures surface velocity rather than radiated acoustic pressure.

Conventional Air-Coupled Microphones

Top out around 100 kHz. They simply cannot characterize MHz-range transducers. BROADSONIC offers 50× the bandwidth.
