The imaging function

Synthax

% prototype
IM = imaging(DIs,IL,MI,Npx)

Description

Function that computes the \(E\) field at the image plane, corresponding to a given set of dipoles at the sample plane. The computation is based on DDA calculations, which take into account dipoles optical coupling.

---

DIs is an array of Dipole objects.

IL and MI are respectively the Illumination and Microscope objects of the setup.

Npx is the size of the image (width and height).

Example

Image simulation

Code that simulates the image of a gold nanoparticle

%% code that simulates the image of a gold nanoparticle

lambda = 530e-9;                    % Illumination wavelength
Npx = 300;                          % Final image with Npx*Npx pixels
n = 1.33;                           % Refractive index of the surrounding medium

ME = Medium(n);
OB = Objective(200,1.3,'Olympus');
CGcam = CGcamera('Silios_mono');
MI = Microscope(OB,180,CGcam);
IL = Illumination(lambda,ME);

DI = Dipole('Au',radius);
DI = DI.shine(IL);
