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

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

“The comparison between Coleridge and Johnson is obvious in so far as each held sway chiefly by the power of his tongue. The difference between their methods is so marked that it is tempting, but also unnecessary, to judge one to be inferior to the other. Johnson was robust, combative, and concrete; Coleridge was the opposite. The contrast was perhaps in his mind when he said of Johnson: “his bow-wow manner must have had a good deal to do with the effect produced.””
—Virginia Woolf (1882–1941)

“A murderer is regarded by the conventional world as something almost monstrous, but a murderer to himself is only an ordinary man.... It is only if the murderer is a good man that he can be regarded as monstrous.”
—Graham Greene (1904–1991)

“A liberal is a socialist with a wife and two children.”
—Anonymous. BBC Radio 4 (April 8, 1990)

“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)
