在MATLAB中,我们可以利用其强大的图像处理库和物理模型来模拟氦氖激光器的单缝夫琅禾费衍射。下面是一个简单的示例代码片段,它假设你已经安装了`physmod`工具箱,用于光学物理计算:
```Matlab
% 导入所需库
import physmod.*;
% 激光器和单缝参数设置
wavelength = 632.8e-9; % 氦氖激光波长 (nm)
laser_power = 1; % 激光功率 (W)
slit_width = 1e-4; % 单缝宽度 (m)
distance_to_screen = 1; % 屏幕到单缝的距离 (m)
% 创建激光源
laser_source = LightSource('Laser', wavelength, laser_power);
% 定义屏幕和单缝的位置
screen_size = 0.1; % 屏幕大小 (m)
screen_center = [0, 0]; % 屏幕中心坐标
% 创建单缝
slit = OpticalElement('SingleSlit', slit_width, screen_center(1), screen_center(2));
% 创建夫琅禾费衍射系统
diffraction_system = System;
diffraction_system.append(laser_source);
diffraction_system.append(slit);
diffraction_system.append(SpatialDetector(screen_size, screen_size, 'Intensity'));
% 进行衍射计算并获取光强分布
[output_image, output_data] = simulate(diffraction_system);
% 可视化结果
figure;
imagesc(output_data);
