Our "Motion Scope tracker" can resolve minute shifts caused by changes in the index of refraction in air enabling for the visualization of Schlieren-like photography, commonly known as Background Oriented Schlieren.
For more about the technology navigate to TECHNOLOGY / BOSchlieren.
For more examples see GALLERY / BOSchlieren.
The technology can be used to measure various objects as it does not require a parabolic mirror.
All our "tracker" systems enable the technology.
