2. Acoustic camera - Wikipedia

   en.wikipedia.org/wiki/Acoustic_camera

   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.

3. Scanning acoustic microscope - Wikipedia

   en.wikipedia.org/wiki/Scanning_acoustic_microscope

   When the acoustic wave propagates though the sample it may be scattered, absorbed or reflected at media interfaces. Thus, the technique registers the echo generated by the acoustic impedance (Z) contrast between two materials. Scanning acoustic microscopy works by directing focused sound from a transducer at a small point on a target object.

4. Acoustic microscopy - Wikipedia

   en.wikipedia.org/wiki/Acoustic_microscopy

   The notion of acoustic microscopy dates back to 1936 when S. Ya. Sokolov [1] proposed a device for producing magnified views of structure with 3-GHz sound waves. However, due to technological limitations at the time, no such instrument could be constructed, and it was not until 1959 that Dunn and Fry [2] performed the first acoustic microscopy experiments, though not at very high frequencies.

5. Photoacoustic imaging - Wikipedia

   en.wikipedia.org/wiki/Photoacoustic_imaging

   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.

6. List of camera types - Wikipedia

   en.wikipedia.org/wiki/List_of_camera_types

   Magnetic resonance imaging which produce images showing, internal structure of different parts of a patient's body. Rangefinder camera which produce images of the distance to each point in the scene. Ultrasonography uses ultrasonic cameras that produce images of the absorption of ultra-sonic energy.

7. PCO Imaging - Wikipedia

   The pco.flim CMOS camera can be used for a vast variety of biomedical applications that require a large frame and high-speed acquisition. [ 11 ] [ 12 ] The new technology for sCMOS (scientific CMOS) image sensors was launched in 2009 during the Laser World of Photonics fair in Munich as Joint Venture from PCO with the companies Andor Technology ...
