ABSTRACT In optical heterodyne detection the alignment of the local oscillator beam and the signal beam is of vital importance. A method for measuring signal -to -noise ratio in a heterodyne system using a blackbody radiation source is presented. Also, amethod for measuring phase front differences between signal beam and local oscillator is described. 1. INTRODUCTION Optical heterodyne detection is often used in telecommunication, signal processing, laser radar and remote sensing systems.The… CONTINUE READING
