03 — Measurement Principles
From Light Scattering to Measurement Information
Our technology is based on incoherent light scattering from individual droplets or particles. Optical instruments record the resulting light-scattering signatures, including their temporal structure. AI-based analysis uses this information to determine properties such as droplet size, velocity, composition and concentration, depending on the measurement configuration and model.
| Platform | Input data | Output data |
|---|---|---|
| SprayQuantAI® | Time-resolved signals from individual droplets | Droplet size, velocity and number |
| ParticleTensorAI® | Buffered light-scattering signal sequences of droplets | Tensor light scattering for labeling |
| SprayConeAI® | Images of sprays and spray patterns | Spray cone parameter |
04 — Spray Analysis · Spray Monitoring
AI for Spray Analysis and Spray Monitoring
Our products address two main tasks: AI-based spray analysis and AI-based spray monitoring.
Spray Analysis
In spray analysis, the focus is on determining droplet properties and their distributions to understand and characterize the spray.
Spray Monitoring
In spray monitoring, the user teaches the system a reference spray condition. During operation, the AI compares the measured signals with this reference to detect deviations and help maintain stable process conditions.
