Laser-Induced Fluorescence (LIF)
Highly selective, high spatiotemporal resolution optical diagnostics for density, velocity distribution, and temperature.
Key Features
- Strong selectivity to target species, high immunity to interference
- 2D/3D density mapping
- Wavelength scans for Doppler broadening → VDF/IVDF and temperature
- Detects trace species with ns-level temporal resolution
