Supersonic Shock Waves of a T-38C Aircraft
This schlieren image of a T-38C aircraft was captured using the patent-pending BOSCO technique and then processed with NASA-developed code to reveal shock wave structures. Researchers at Armstrong and NASA’s Ames Research Center at Moffett Field, California, have developed new schlieren techniques based on modern image processing methods. To source
