Measurement and visualization of sound wave pressure fields using laser Doppler interferometers and scanning arrangements so that a wide range of sound frequencies and intensities can be visualized
Measurement and visualization of sound wave pressure fields using laser Doppler interferometers and scanning arrangements so that a wide range of sound frequencies and intensities can be visualized
Arrangement for measurement and visualization of sound pressure fields in transparent gases using a laser Doppler interferometer (1) with scanning device (2) for point-wise 2-D imaging of sound pressure field (3). Scanner directs laser beam towards fixed reflector (5) and analysis unit (4) uses interference between reflected and reference beams and resultant frequency increase according to known method to visually display sound wave field.
