Optical Heterodyne Detection - Contrast To Conventional Radio Frequency (RF) Heterodyne Detection

Famous quotes containing the words contrast, conventional, radio and/or frequency:

“In contrast to revenge, which is the natural, automatic reaction to transgression and which, because of the irreversibility of the action process can be expected and even calculated, the act of forgiving can never be predicted; it is the only reaction that acts in an unexpected way and thus retains, though being a reaction, something of the original character of action.”
—Hannah Arendt (1906–1975)

“It is conventional to call “monster” any blending of dissonant elements.... I call “monster” every original inexhaustible beauty.”
—Alfred Jarry (1873–1907)

“from above, thin squeaks of radio static,
The captured fume of space foams in our ears—”
—Hart Crane (1899–1932)

“The frequency of personal questions grows in direct proportion to your increasing girth. . . . No one would ask a man such a personally invasive question as “Is your wife having natural childbirth or is she planning to be knocked out?” But someone might ask that of you. No matter how much you wish for privacy, your pregnancy is a public event to which everyone feels invited.”
—Jean Marzollo (20th century)
