System and method to provide material property measurement using re-entrant ultrasound
Abstract
Presented is a system and method for performing highly sensitive measurement of ultrasonic attenuation in small material volumes. The invention allows the mapping of the variations on the surface of a specimen with a high spatial resolution. An ultrasonic transmitter and receiver transmit an ultrasonic signal through a material volume, receive the transmitted pulse, and then re-transmit the received pulse again through the same material volume. The system establishes an oscillating circuit by establishing a positive feedback loop by connecting the transmitter to the receiver with appropriate gain. This oscillating circuit contains the propagation through the material as a component in the signal path. Such a system and method may be employed to aid in the recovery of stamped or engraved serial numbers that have been removed through machining. Such recovery is useful for law enforcement, particularly in tracing weapons and auto parts that have been involved in a crime.
