Abstract: An apparatus for imaging structural features below the surface of an object, the apparatus comprising: a transmitter unit configured to transmit a sound pulse at the object; a receiver unit configured to receive reflections of sound pulses transmitted by the transmitter unit from the object; a signal processing unit configured to: analyse one or more signals received by the receiver unit from the object; recognise, in the one or more signals, a reflection that was caused by a first structural feature and a reflection that was caused by a second structural feature that is located, in the object, at least partly behind the first structural feature; and associate each recognised reflection with a relative depth in the object at which the reflection occurred; and an image generation unit configured to generate an image that includes a representation of the first and second structural features in dependence on the recognised reflections and their relative depths.

Abstract: A sensing apparatus comprising an ultrasound transceiver for transmitting ultrasound signals into a sample and receiving a resultant ultrasound reflection signal from the sample, a detector for processing signals received by the transceiver by comparing the received signal against a reference signal to generate a response signal, the response signal comprising values as a function of time that represent the strength of the match between the received signal and the reference signal at the respective time; and a driver capable of generating a plurality of pre-defined pulse templates.

Abstract: An apparatus for imaging structural features below the surface of an object, comprising: an analysis unit configured to gather information about structural features located at different depths below the surface of the object by transmitting one or more sound pulses at the object and detecting reflections of those sound pulses from the object; and an image generation unit configured to generate: a first image in dependence on a first subset of the detected reflections, the first image representing an overview in which one or more of the structural features may be obscured by another of the structural features; and a second image in dependence on a second subset of the detected reflections, the second image representing a slice through the first image whereby the obscured structural features can be uncovered.
