Schlieren method [Application example of high-speed camera]
If you can assemble an optical system, you can qualitatively observe density changes in any phenomenon!
The "Schlieren method" is a technique that visualizes subtle density changes in gases, which cannot be seen with the naked eye, by using a special optical system to refract light. In high-speed camera imaging, the Schlieren method can be used to visualize fluctuations in gases before combustion in internal combustion engines, shock waves that occur in regions exceeding the speed of sound, and the resistance experienced by aircraft bodies as a result. If an optical system can be assembled, density changes of any phenomenon can be qualitatively observed, making it a very convenient visualization technique used in many situations. 【Imaging Equipment (Partial)】 ■ High-Speed Camera MEMRECAM ACS-1 - ISO Sensitivity Color/Monochrome: 5,000–40,000/25,000–200,000 - Resolution: 1,280×896 pixels - Shooting Speed: 50–1,000,000 fps - Recording Time Normal Mode: Approximately 2.8 seconds (60,000 fps, 256GB, 12bit) *For more details, please refer to the related links or feel free to contact us.
