Abstract : The patent describes a photomultiplier (PM) tube for a laser velocimeter in which electrodes are used in conjunction with a local oscillator signal to permit frequency heterodyning to extend the useful frequency response range of the photomultiplier tube. The heterodyne PM tube is then used as a component in a superheterodyne type signal conditioning instrument for a doppler shift laser velocimeter (LV).
