Pattern
Representative sound field computation utilities such as a single focal point, a plane wave, and a Bessel beam.
Function List
Section titled “Function List”- focus — single focal point
- plane — plane wave
- bessel — Bessel beam
- uniform — uniform over all transducers
- null — no output
Each function also has a *_device variant that computes for only a single device, and a *_transducer variant that computes for only a single transducer element (for example, focus_device / focus_transducer).
Wavelength
Section titled “Wavelength”The phase computation requires the wavelength autd3_rs_pattern::wavelength(sound_speed).
At a sound speed of 340 m/s (the speed of sound in air at a room temperature of about 15°C),
