Theory of stabilized autodyne oscillators at the large reflected signal

, 2011
Research results on autodyne oscillator stabilized by an external high-Q cavity are presented for the case of the large reflected signal, when amplitude of the reflected wave is commensurable with amplitude of natural oscillations. Expressions describing

Laser Optical Feedback Imaging (LOFI) controlled by an electronic feedback loop.

, 2013
International audienceIn autodyne interferometry, the beating between the reference beam and the signal beam takes place inside the laser cavity and therefore the laser fulfills simultaneously the roles of emitter and detector of photons.

Theoretical grounds of autodyne method of forming response signals of a radiosonde for distance measurements

, 2012
This report describes the operation principle and block diagram of the autodyne transceiver proposed for the atmosphere radio probing system. The transceiver has better electromagnetic compatibility as compared with currently used superregenerative ...

Optimization of an autodyne laser interferometer for high-speed confocal imaging

, 2012
International audienceIn autodyne interferometry, the beating between the reference beam and the signal beam takes place inside the laser cavity and therefore the laser fulfills simultaneously the roles of emitter and detector of photons.

Analysis of signals of stabilized autodynes

, 2011
Results of the autodyne signal analysis of the self-oscillating systems stabilized in frequency by the external high-quality cavity are given. The coupling between the main and stabilizing cavities is realized on the basis of a pass-reflective filter ...
