ABSTRACT:
A solid-block homodyne Doppler interferometer utilizing continuous-wave or pulse-wave light beam technology. A pulse-wave light beam version of the homodyne interferometer compares the pulse-wave return signal with a continuous-wave local oscillator signal, thereby permitting the interferometer to be utilized over a wide range of distances.
