Abstract

A MHz rate Shack-Hartmann sensor has been built which allows the measurement of wavefront phase distortion in high speed flows. It is capable of obtaining 30 frame movies at up to 500 kHz or 1 MHz with a 2 ps pause at every fifth frame. The sensor was used to obtain the distortion due to flow over a wedge at Mach 2.4 at a 7.8 kHz framing rate. It was also used at 500 kHz to measure the optical path difference due to a nitrogen free jet and due to a hypersonic boundary layer at Mach 8. Results are promising and the system is still under further development.
