In astronomical spectroscopy more efficient use of the incident flux and ever higher resolution are of utmost concern. The optical heterodyne technique using a laser as a local oscillator is a means of down converting optical frequencies to radio frequencies in what is termed electronic spectroscopy. It is a non-dispersive technique which does not require entrance slits; its chromatic resolving power, limited primarily by the bandpass of the associated electronics, can be considerably greater than conventional optical techniques. Although conditions for successful operation of the technique are better in the infra-red, the current work is directed at visible wavelengths where such high resolution is a necessity. In this work, confusion in signal brought about by double sideband detection is considered and shown that at least for single frequencies one sideband can be suppressed by as much as 54db.
