It is shown that 3D-pattern recognition methods combined with acoustic holography methods are a promising tool for atomization of measurements used in the physical chemistry of polymer hydrogels, in particular, for studying the interaction of hydrogels with substances present in the surrounding solution. It is shown that in this case, simplified methods for obtaining 3D patterns can be used. The convenience of using Galois fields for obtaining information and phase shifts of acoustic oscillations has been demonstrated. A modulo adder circuit with an adjustable value of the modulus is proposed, which makes it possible to significantly simplify the circuit implementation of calculations in Galois fields.
