MODELING THE PROCESS OF OBTAINING A STIGMATIC IMAGE OF AN ACOUSTIC OBJECT IN AN ACOUSTO-OPTIC VISUALIZATION DEVICE

Annotation

A method of acousto-optic visualization of spatially inhomogeneous acoustic fields formed by acoustic object is considered. This method is based on Bragg diffraction in a system with a double Fourier transform. Among the advantages of the device that implements this method, there is a high resolution. It is shown analytically that, in contrast to the well-known visualization technique by A. Korpel, the images of acoustic micro-objects obtained with using the proposed a device, are free from astigmatism. As a result of theoretical analysis of the device operation mechanism, equations for calculating the geometric parameters of optical image of acoustic micro-object are derived.
