bessel

bessel はベッセルビームを生成する. アルゴリズムは長谷川らの論文 (Hasegawa et al., 2017) に基づく.

API

Rust

bessel(&geometry, apex, direction, theta, wavelength, &mut phases);

Python

bessel(geometry, apex, direction, theta, wavelength, phases)

C#

Pattern.Bessel(geometry, apex, direction, theta, wavelength, phases);

引数	型	説明
geometry	&Geometry	デバイス配置
apex	Point3<f32>	ビームを生成する仮想円錐の頂点座標 [mm]
direction	UnitVector3<f32>	ビームの方向 (単位ベクトル)
theta	Angle	円錐の半頂角 (18.0 * deg など)
wavelength	Length	波長
dst	&mut [Vec<Phase>]	出力バッファ

Example

Rust

use autd3_rs::geometry::{Autd3, Geometry, Vector3, offset};
use autd3_rs::units::{deg, m, mm, s};
use autd3_rs_pattern::{bessel, wavelength};

let geometry = Geometry::new(vec![Autd3::default()]);

let mut phases = geometry.phase_buffer();

bessel(
    &geometry,
    geometry.center() + offset(0.0 * mm, 0.0 * mm, 150.0 * mm),
    Vector3::z_axis(),
    18.0 * deg,
    wavelength(340.0 * m / s),
    &mut phases,
);

Python

import numpy as np
from autd3.geometry import Autd3, Geometry
from autd3.units import deg, m, s
from autd3_pattern import bessel, wavelength

geometry = Geometry([Autd3([0.0, 0.0, 0.0], [1.0, 0.0, 0.0, 0.0])])

phases = geometry.phase_buffer()

bessel(
    geometry,
    geometry.center() + np.array([0.0, 0.0, 150.0]),
    np.array([0.0, 0.0, 1.0]),
    18.0 * deg,
    wavelength(340 * m / s),
    phases,
)

C#

using System.Numerics;
using AUTD3;
using static AUTD3.Units;

var geometry = new Geometry(new[] { new Autd3(Vector3.Zero) });

var phases = geometry.PhaseBuffer();

Pattern.Bessel(
    geometry,
    geometry.Center + new Vector3(0.0f, 0.0f, 150.0f),
    Vector3.UnitZ,
    18.0f * deg,
    Pattern.Wavelength(340.0f * m / s),
    phases
);
