heterodyne in English
adjective
1
of or relating to the production of a lower frequency from the combination of two almost equal high frequencies, as used in radio transmission.
The system achieves this by measuring the target velocity of the cylinder carrier from optical phase shift, using an optical heterodyne interferometer to exploit the temporal, rather than spatial, coherence of the laser.
verb
1
combine (a high-frequency signal) with another to produce a lower frequency in this way.
When the two frequencies were mixed, or heterodyned , the difference between them resulted in a third frequency; it was this so-called ‘difference tone’ that was amplified and channeled to a loudspeaker.
