Paper Abstract

Methods of converting schlieren systems into interferometers for high speed applications have been studied both theoretically and experimentally. Theoretical analyses include dark central ground, field absorption (also called point diffraction), and phase contrast interferometers. Experimentally, dark central ground and field absorption has been used in a 45 cm diameter double pass schlieren to produce infinite fringe interferograms of projectiles flying at approximately 1600 m/s. The latter was done in the Aeroballistics Research Facility, Eglin AFB without special attention being given to vibration or to temperature changes. Some possible vibration effects are discussed.
