Paper 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, a method for measuring phase front differences between signal beam and local oscillator is described.
