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.
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.
Portable ultrasound is a modality of medical ultrasonography that utilizes small and light devices, compared to the console-style ultrasound machines that preceded them. In most cases these mobile ultrasound systems could be carried by hand and in some cases even operated for a time on battery power alone.
Schlieren imaging is a method to visualize density variations in transparent media. [ 1 ] Schlieren imaging of a focusing ultrasonic transducer Schlieren image sequence of a bullet traveling in free-flight, demonstrating the air pressure dynamics surrounding the bullet

Acoustic location is a method of determining the position of an object or sound source by using sound waves. Location can take place in gases (such as the atmosphere), liquids (such as water), and in solids (such as in the earth).
A thermal imaging camera (colloquially known as a TIC) is a type of the thermographic camera used in firefighting. By rendering infrared radiation as visible light , such cameras allow firefighters to see areas of heat through smoke, darkness, or heat-permeable barriers.
