The light signal is compared with standard or reference light from a "local oscillator" (LO) that would have a fixed offset in frequency and phase from the signal if the latter carried null information. "Heterodyne" signifies more than one frequency, in contrast to the single frequency …

WebJul 18, 2000 · Two-dimensional infrared spectra of peptides are introduced that are the direct analogues of two- and three-pulse multiple quantum NMR. Phase matching and heterodyning are used to isolate the phase and amplitudes of the electric fields of vibrational photon echoes as a function of multiple pulse delays. WebThe difference-frequency oscillations, which correspond to heterodyning single-photon pairs, are also robust in the presence of dispersion, though they decay for large path-length-differences. Potential areas of applicability of twin photon beams range from photonics to visual science to computer science.
