Sonar tomography
Did you know?
Photoacoustic imaging or optoacoustic imaging is a biomedical imaging modality based on the photoacoustic effect. Non-ionizing laser pulses are delivered into biological tissues and part of the energy will be absorbed and converted into heat, leading to transient thermoelastic expansion and thus wideband (i.e. MHz) ultrasonic emission. The generated ultrasonic waves are d… WebAlso, optical images lack the range information found in sonar images. The performance of an imaging sonar—from the distance at which they can detect an object, to the clarity of …
