What is Acoustic Imaging?
Limitation of Human Perception
The human ear can only perceive sounds in the range of 20 Hz to 20 kHz. However, hidden faults such as gas leaks, bearing wear, and electrical discharges often emit much higher frequency ultrasound (>20 kHz) — sounds that are imperceptible to the human ear and beyond the capabilities of traditional stethoscopes or microphones.

How does it work?

-
Microphone Array: Simultaneously captures sound signals from multiple sources to enhance spatial accuracy.
-
Beamforming Algorithm: Focuses on sound sources from specific directions, filtering out environmental noise.
-
Acoustic Image Overlay: Displays sound source locations as a heatmap over the image.
-
Low-Latency Rendering Engine: Enables near-instant response, ideal for continuous inspection scenarios.
Beyond What's Audible
The FOTRIC TD2e acoustic imaging camera can detect not only audible sound, but also highfrequency ultrasonic signals that are beyond the range of human hearing.
This means it can easily capture things like:
Compressed Air System Leaks
As gas leaks emit high-frequency turbulence noise, the TD2e can quickly detect even the smallest leaks in compressed air pipelines.


Vacuum System Leaks
The TD2e precisely captures subtle leak sounds in vacuum systems that human ears cannot hear, enabling fast leak localization without contact or damage to equipment.


Loose Joint Vibration During Operation
The TD2e detects abnormal highfrequency sounds caused by loose screws while equipment is running. It visualizes and pinpoints the issue in real time without requiring a shutdown.


Pneumatic Valve Leakage Detection
As pneumatic valves, cylinders, and fittings in automated production lines age, they frequently generate high-frequency leakage noise. The TD2e captures real-time ultrasonic leakage signals from valve bodies and fittings, providing visual localization to pinpoint leak sources quickly.

Professional-grade Features
Multiple Image Modes
Even in noisy environments, sound sources no longer blur into one. Multisource mode can simultaneously lock onto multiple abnormal sound points, automatically distinguish sources with different frequencies and intensities, and enable multi-target visualization—making every issue clearly visible.



Single-source
Multi-source
All-source
Dual Detection Mode
Noise Suppression Mode: Maintains stable acoustic imaging even in high-noise environments, accurately locating true sound sources.
Micro-Detection Mode: Captures subtle sounds, ensuring no potential issue points are missed.
