`x= 1:150;y=1:150;[p,q]=freqspace(150);[X,Y]=meshgrid(p,q);R=(X.^2 + Y.^2);Lambda=633*10^-9;dis=10*10^-3;F = (exp(i.*pi.*R))./(Lambda.*dis);kernel = imag(F); % Gray scale image = imaginary part.`

mesh(kernel);axis squareimshow(kernel, []);axis on;colormap(gray(256));rgbImage = imread('image.jpg');imshow(rgbImage);axis on;% R=rgbImage(:,:,1);

% G=rgbImage(:,:,2);

% B=rgbImage(:,:,3);

grayImage = rgb2gray(rgbImage);imshow(grayImage, []);axis on; grayImage1=fft2(double(grayImage)); kernel1=fft2(kernel); Imagef=kernel*grayImage1;Imagefinal=ifft2(Imagef);imshow(Imagefinal, []);axis on;this code has no error.its output should be like hazy image of concentrating circle or may be overlapp.but it shows hazy straight line.please help
