摘要： The invention relates to an optical device (10) for determining a physical parameter which comprises: a laser diode (11) for emitting a beam toward a target; a means for detecting (13) an interferometric signal SM(t) which comprises the information on the physical parameter to be determined, and which is generated by an interference between the emitted beam and a light beam reflected by the target; means for converting (15) the signal SM(t) obtained by the detection means (13) into a measurement of the physical parameter, said conversion means (15) comprising: first means (17) for suppressing a continuous component Off(t) of the interferometric signal SM(t); second means (18) for determining interferometric peaks in the interferometric signal SM(t) obtained from the signal obtained at the output of the first means (17). The invention also relates to an associated method. Said method is particularly suitable for speckle interferometric signals.

摘要： This analogue amplification device comprises -a first stage (28) with common-base transistor (36) receiving the modulated input current entering its emitter, and the output signal leaving this first stage corresponds to the signal of the collector, - a second stage (30) is formed by a follower amplifier comprising a transistor (38) with common drain or collector setup, a third stage (52) comprises a transistor (40) with common emitter setup, and - a fourth stage (34) is an amplifier stage with means making it possible to carry out, on the one hand, an amplification and, on the other hand, a matching of impedance. Application to a laser anemometer with optical retro-injection.
