Title (EN) AN IMPROVED INTERFEROMETRIC AMPLIFIER
(FR) AMPLIFICATEUR INTERFEROMETRIQUE PERFECTIONNE
Abstract:
(EN) Improved interferometric amplification is achieved by separating (21, 22, 31, 32) the input signal in accordance with the signals projection on two orthogonal reference signals, with one of the reference signals capable of following the instantaneous frequency of the input signal. The separated signals are further separated (41, 42) into constant amplitude variable phase signal pairs defining the projected signals, and the constant amplitude signals are amplified (51, 52, 53, 54) and appropriately combined (61, 62, 63) to form a signal that is an amplified replica of the input signal.
(FR) On obtient une amplification interferometrique perfectionnee en separant (21, 22, 31, 32) le signal d"entree en fonction de sa projection sur deux signaux de reference orthogonaux, l"un de ces signaux de reference etant capable de suivre la frequence instantanee du signal d"entree. Les signaux separes sont a nouveau separes (41, 42) en paires de signaux d"amplitude constante et a phase variable definissant les signaux projetes, et les signaux d"amplitude constante sont amplifies (51, 52, 53, 54) et combines de facon appropriee (61, 62, 63) pour former un signal qui est une replique amplifiee du signal d"entree.
