focus

focus generates a single focal point.

API

Rust

focus(&geometry, target, wavelength, &mut phases);

Python

focus(geometry, target, wavelength, phases)

C#

Pattern.Focus(geometry, target, wavelength, phases);

Parameter	Type	Description
geometry	&Geometry	Device layout
target	Point3<f32>	Focal point coordinates [mm]
wavelength	Length	Wavelength
dst	&mut [Vec<Phase>]	Output buffer

Example

Rust

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

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

let mut phases = geometry.phase_buffer();

focus(
    &geometry,
    geometry.center() + offset(0.0 * mm, 0.0 * mm, 150.0 * mm),
    wavelength(340.0 * m / s),
    &mut phases,
);

Python

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

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

phases = geometry.phase_buffer()

focus(
    geometry,
    geometry.center() + np.array([0.0, 0.0, 150.0]),
    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.Focus(
    geometry,
    geometry.Center + new Vector3(0.0f, 0.0f, 150.0f),
    Pattern.Wavelength(340.0f * m / s),
    phases
);
