Dual-Line Laser-Induced Testing System

Apr 09, 2026

The Dual-Line Laser-Induced Testing System is a high-precision, non-intrusive optical testing device, mainly used for the detection and analysis of transient flow fields, combustion processes and reactive species. It adopts dual-line laser induction technology, which can effectively avoid mutual interference between detection channels and realize high-precision synchronous testing of multiple physical quantities.

Key technical specifications:

Dual-line synchronous output; two wavelengths can be modulated for synchronous excitation as needed, such as two components: CH,NH,OH,NO, etc., which are used for the tracking of two process components and the research on their generation mechanisms; or two excitation lines of the same component, such as the Q1(6),Q1(8),Q1(12) of OH radicals, etc., which are used for the detection of the distribution characteristics of physical quantity fields such as temperature.

Maximum repetition rate: 10 Hz;

Synchronization accuracy: Nanosecond level;

Temporal resolution: Capable of capturing transient dynamic processes at the millisecond to microsecond level;

Sensitivity: Capable of detecting weak fluorescence and scattering signals.

The system supports the quantitative measurement of flow velocity, species concentration, flame temperature and reaction zone distribution, and is widely applicable to fields such as fundamental combustion research, aero-engine thermal flow diagnosis and industrial process monitoring, providing reliable experimental data and technical support for related research and engineering applications.
