"We have developed a modern retro-reflective shadowgraph system for the visualization of refractive flows, especially shock wave and heat convection applications. This shadowgraph system uses a 2.4 x 2.4 m retro-reflective screen, white-light arc lamp source, and is compatible with digital cameras. This simple and portable system has been used in a wide variety of experiments both inside and outside of the laboratory."
