An acoustic camera (or noise camera) is an imaging device used to locate sound sources and to characterize them. It consists of a group of microphones, also called a microphone array , from which signals are simultaneously collected and processed to form a representation of the location of the sound sources.
Fig. 4: Generic thermoacoustic imaging instrumentation. Any thermoacoustic imaging device requires a source of electromagnetic radiation, be it a laser or a microwave antenna, to deliver energy to the anatomy being studied, and one or more acoustic detectors coupled acoustically to the outside surface of the anatomy, as is illustrated in Fig. 4.
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 term camera is also used, for devices producing images or image sequences from measurements of the physical world, or when the image formation cannot be described as photographic: Acoustic camera which makes sound visible in three dimensions
Thermal acoustic imaging (TAI) is a proprietary active thermographic inspection process developed by Pratt and Whitney (P&W) in 2005; TAI is a nondestructive testing (NDT) method to detect internal and external cracking of hollow core turbofan engine fan blades.
A scanning acoustic microscope (SAM) is a device which uses focused sound to investigate, measure, or image an object (a process called scanning acoustic tomography). It is commonly used in failure analysis and non-destructive evaluation .
