Pattern

Representative sound field computation utilities such as a single focal point, a plane wave, a Bessel beam, a Laguerre-Gaussian beam, and a Hermite-Gaussian beam.

Installation

Rust

cargo add autd3-rs-pattern

Python

pip install autd3-pattern

C#

dotnet add package AUTD3.Pattern

Function List

• focus — single focal point
• plane — plane wave
• bessel — Bessel beam
• laguerre_gaussian_phase / laguerre_gaussian_intensity — phase and intensity of a Laguerre-Gaussian beam
• hermite_gaussian_phase / hermite_gaussian_intensity — phase and intensity of a Hermite-Gaussian beam

focus / plane / bessel / laguerre_gaussian_phase / hermite_gaussian_phase also have a *_transducer variant that returns the phase of a single transducer element (for example, focus_transducer). laguerre_gaussian_intensity / hermite_gaussian_intensity have no per-transducer variant.

Wavelength

The phase computation requires the wavelength . The wavelength can be obtained from the sound speed via autd3_rs_pattern::wavelength(sound_speed) (Python: autd3_pattern.wavelength, C#: Pattern.Wavelength). At a sound speed of 340 m/s (the speed of sound in air at a room temperature of about 15°C), .
