WebApr 11, 2024 · It was not a great leap for Binder to imagine the electrons moving along the metal and releasing a photon again at another location. ... His invisibility is based on heterodyning: the mixing of signals of two different frequencies to produce a higher or lower frequency output. Heterodyning is used to produce the audible output signals in radio ... Optical heterodyne detection is a method of extracting information encoded as modulation of the phase, frequency or both of electromagnetic radiation in the wavelength band of visible or infrared light. 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 …
