摘要： Mechanical vibration may be sensed by a remotely located ultrasonic sensor. An ultrasonic wave may be transmitted from a transmitter to a vibrating surface, in which the transmitter is separated from the vibrating surface by a distance. A reflected portion of the ultrasonic wave that is reflected from the vibrating surface may be received by a receiver that is also separated from the vibrating surface by a distance. A measure of phase shift amplitude in the reflected portion of the ultrasonic wave may be determined and converted into an amplitude of a vibration of the vibrating surface.

摘要： A patch and associated methods for monitoring and inspecting a structure are provided in order to facilitate such inspections. The patch includes a sheet of material configured to be attached to the structure and a frequency steerable array carried by the sheet of material. The frequency steerable array includes a plurality of sources for emitting structural waves in response to an input having a variable frequency such that variations in the frequency of the input cause the structural waves emitted by the plurality of sources to be controllably steered relative to the sheet of material. Methods utilizing one or more frequency steerable arrays for monitoring and inspecting a patch-repaired structure are also provided.

摘要： A non-intrusive sensor for in-situ measurement of recession rate of heat shield ablatives. An ultrasonic wave source is carried in the housing. A microphone is also carried in the housing, for collecting the reflected ultrasonic waves from an interface surface of the ablative material. A time phasing control circuit is also included for time-phasing the ultrasonic wave source so that the waves reflected from the interface surface of the ablative material focus on the microphone, to maximize the acoustic pressure detected by the microphone and to mitigate acoustic velocity variation effects through the material through a de-coupling process that involves a software algorithm. A software circuit for computing the location off of which the ultrasonic waves scattered to focus back at the microphone is also included, so that the recession rate of the heat shield ablative may be monitored in real-time through the scan-focus approach.

摘要： An opto-acoustic transducer assembly includes a substrate; at least one layer of opto-acoustic material coupled to a surface of the substrate, where the at least one layer of opto-acoustic material generates sound waves when struck by pulses of pump light; and an acoustic lens configured to focus sound waves generated by the at least one layer of opto-acoustic material towards a sample. The acoustic lens is further configured to collect sound waves returning from the sample and to direct the returning sound waves to the at least one layer of opto-acoustic material. The at least one layer of opto-acoustic material is responsive to the returning sound waves for having at least one optical property thereof changed, where the change is detectable from a change in a characteristic of reflected pulses of probe light that are time delayed with respect to the pulses of pump light.

摘要： Embodiments of techniques to verify the interference fit of fasteners are disclosed. In one embodiment, a method includes aligning a probe proximate a fastener, the fastener being disposed within a material. A dynamic stress signal is generated from the probe using a low frequency transducer, and the dynamic stress signal is interrogated after it passes between the fastener and the material. An interference fit is then determined based on the interrogated dynamic stress signal.
