Abstract

The paper considers the schematic diagram and operation algorithm of acoustooptic processor (AOP), the main assemblies of which are acoustooptic modulator (AOM), laser and photodetector (PD). Using the mathematical simulation, it has been shown that the signal at the AOP output contains information about the characteristics of AOM, laser and PD. The possibility of investigating the characteristics of one of the above assemblies with the known parameters of the other two by using the AOP response on determinate input action in the form of rectangular pulse has been established. A brief review of the known methods for measuring the parameters of PD and laser is presented including certain limitations of their applications. The theoretical substantiation of the possible use of AOP peculiarities for measuring the PD inertia parameters is presented. A formula for the calculation of the AOP output response to rectangular input action is proposed that makes it possible to estimate separately the time of optical beam crossing by the elastic wave packet and PD inertia. In addition, it has been proved that the configuration of cross-section of laser beam and the distribution law of power flux density in this beam could be determined on the basis of AOP peculiarities. To this end, a pulse of short duration is fed to the AOP input. Results of theoretical investigations were validated by numerical calculations and confirmed by experimental measurements.
