Schlieren imaging of aircraft in flight using photography of the solar limb was first demonstrated in the 1990s, but the technique was relatively cumbersome with the film cameras of the time. The improvement of high-speed digital camera technology and image processing has allowed the development of an improved method for producing schlieren images of aircraft and aerooptic effects, which requires only a simple telescope and a digital video camera. The underlying processing techniques are described along with results from field tests of such a system.
