Abstract:

In this report, the development of a prototype instrument to measure the velocity of particles in the exhaust of a solid rocket motor is described. The measurement technique is based upon the doppler-shifted scattering of a focused laser beam by the particle matter in a flow. The absolute value of frequency is converted into velocity information by a Fabry Perot interferometer, photomultiplier, electronic signal processing circuits and a suitable recording device. The recorded data is in the form of signal number count rate and maximum signal amplitude as a function of velocity at a specific point in the flow. This volume describes the development of the prototype instrument. Author
