Acousto-optic laser optical feedback imaging

Hysteresis loops observed on the oscilloscope screen before and after longitudinal E || (instantaneous reaction, not permanent effect) and transverse E ⊥ (gradual

In addition, we present practical applications of OFI sensors as laser velocimeters applied to the detection of flowing particles in a microchannel, the analysis of unsteady flows

Simulation results show that the double feedback forces the oscillator to put the oscillation frequency closer to the natural frequency of the MEMS resonator, even in the case

The first evaluations of sound fields, in this case the velocity of sound in various liquids, were made in 1932. An example of these early efforts is shown in Fig. No

Laboratoire interdisciplinaire de Physique B.P. This simple and efficient technique using frequency-shifted optical feedback needs the sample to be scanned in order to obtain

From equation (20) it is then straightforward to cal- culate the dependence of the acousto-optic signal on Δω for the different detection configurations (phase modula- tion for the

It catalyzed the transfer of the amino group from leucine, methionine, AABA, alanine, cysteine, and phenylalanine to the amino group acceptor α-ketoglutarate..
