Schlieren studies involve visualizing and analyzing the flow of fluids and gases by detecting changes in refractive index. In Schlieren imaging, light rays are deflected by variations in the refractive index caused by density gradients in the medium, allowing researchers to visualize phenomena such as shock waves, heat convection, and supersonic flows. High frame rate cameras capture rapid changes in the refractive index with high temporal resolution, enabling the visualization of dynamic events and phenomena that occur in milliseconds or microseconds. By recording high-frame-rate videos of Schlieren images, researchers can precisely study the behavior of fluids and gases under various conditions, providing valuable insights into aerodynamics, combustion, and fluid mechanics. High-speed cameras enhance the accuracy and detail of Schlieren imaging, facilitating the advancement of research in aerospace engineering, automotive design, and other fields where understanding fluid dynamics is critical.
