Abstract: A method for determining the purity or authenticity of a substance being transported in a container through a supply chain including providing an entry transmitter for generating a multi-frequency coded ultrasonic signal and an entry receiver for receiving said signal after it has passed through the substance and the container, generating an entry identifier of the substance in the container, recording said entry identifier at an entry point of said supply chain, transporting the substance in the container to a destination, providing an exit transmitter for generating a multi-frequency coded ultrasonic signal and an exit receiver for receiving said signal after it has passed through the substance and the container, generating an exit identifier of the substance in the container, and comparing said entry identifier and said exit identifier to determine whether the substance in the container has been altered during travel through the supply chain.

Abstract: An ultrasonic interferometer for the characterization of the matter (solids, fluids & gases) in a medium is described, along with a method of using the same. The interferometer accurately determines the travel time of the multi-frequency ultrasonic signal in the matter that is being queried. By carefully selecting the design of the multi-frequency ultrasound signal, various properties of the material can be derived using a trainable classification system to classify or recognise the substance, or state of a process. The apparatus exploits the normally undesirable higher harmonics characteristics of the piezoceramic transducer to gain penetration through a spatial-frequency window that is not suitable for the higher frequency signals that are required to achieve the measurements.
