Paper Abstract

A heterodyne interferometer is described for measuring transient flow field phenomena. Data are acquired through up to 64 channels in parallel with a dedicated phase meter, digitizer and buffer memory for each channel. Data frame rates can be as high as 100 KHz with instrumental background levels less than 0.8 nm rms. Measured data of an electron-beam or e-beam pumped flow fields will be presented and discussed.
