Digital Schlieren Imaging System
Visualize the invisible. Capture airflows, gas leaks, and thermal gradients with precision and clarity.
What is Schlieren Imaging?
Schlieren imaging is a powerful optical method developed in the 19th century to visualize changes in air and gas density. While gases like hydrogen or CO₂ are invisible to the naked eye, Schlieren reveals their presence by capturing the way light bends when passing through areas of differing density.
What is Digital Schlieren (BOS Method)?
DSS uses Background Oriented Schlieren (BOS) to visualize airflow, thermal convection, and gas dispersion. Unlike traditional Schlieren systems that require complex optics and alignment, BOS uses simple components—camera, background, and light—to deliver high-resolution, real-time Schlieren imaging with minimal setup.
Key Features & Advantages
Plug & Play Design – No lasers or complex optics. Setup in minutes.
Flexible Compatibility – Use your existing camera or choose from our high-speed/high-res models.
Real-Time Visualization – Monitor density changes as they occur with live display and analysis.
High-Precision Algorithms – Developed with Tokyo University of Agriculture and Technology.
Large & Small Scale Applications – From millimeters to meters—capture what others can’t.
One-Stop Software Suite – [Koncerto-DSS] handles measurement, visualization, and analysis.
Common Applications

System Components
Each DSS system is modular and customizable:
| Component | Description |
|---|---|
| High-Speed Camera | e.g., VEO 710, HX-7S – for transient, rapid-flow visualization |
| High-Resolution Camera | e.g., DSS-24MP – for ultra-fine visualization of steady-state phenomena |
| Display Panel Background | Full HD, 4K, or printed patterns depending on flow type and scale |
| Light Source | Ambient, LED, or pulsed depending on application |
| Analysis Software | Koncerto-DSS with real-time vector analysis and high-precision BOS tools |
| Workstation | Laptop or desktop depending on data throughput needs |
