- 11 Oct 2010
TL;DR: In this paper, the authors proposed a device which comprises a means (12) for emitting a laser beam, referred to as an emitted beam; a means(16) for focussing the emitted beam at a predetermined focal distance (D); a means 20 for receiving the emitted beacon after being reflected by means of a particle in the air (18), referred as a reflected beam; and a means 32 for transmitting the signal of interference occurring between the emitted and the reflected beam to a signal processing means (24) in order to deduce the speed of the particle therefrom

Analogue amplification device intended in particular for a laser anemometer
Francis Bony,Raphaël Teysseyre +1 more
- 14 Aug 2013
TL;DR: In this article, an analogue amplification device consisting of a first stage (28) with a 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, is formed by a follower amplifier comprising a transistor (38) with common drain or collector setup, a third stage (52) comprises a transistor 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,
