Article Synopsis
- This study presents new methods for accurately capturing and analyzing weak airflow using background-oriented schlieren techniques.
- It involves designing a specific background texture and sensor layout, as well as utilizing a correlation matrix for image analysis and calculating the density field with Poisson's equation.
- The effectiveness of these methods was confirmed through combustion experiments and quad-rotor UAV tests, successfully revealing complex laminar flow structures despite challenges from weak airflow and large views.
