ZernikeReconstruct

MATLAB

img_out = ZernikeReconstruct(orders,coeffs,r,t)

Produces phase screen given Zernike orders to be used and their corresponding magnitudes (coefficients)

Parameters	Description
orders [vector]	Zernike orders for which reconstruction is to be computed
coeffs [vector]	Coefficients for magnitude of Zernike orders
r [matrix]	Radius values
t [matrix]	Theta values

Return Values	Description
img_out [matrix]	Reconstructed image

>> x = ((1:64)-(64/2+1))*0.01;

>> [y,x] = meshgrid(x,x);

>> rad = sqrt(x.^2+y.^2);

>> theta = atan2(y,x);

>> ApRad = 0.25;

>> mask = (rad<=ApRad);

>> rho = rad./ApRad;

>> z = ZernikePolynomial(5,rho,theta);

>> c = ZernikeCoefficient(z.*mask,[2:11],rho,theta);

>> p = ZernikeReconstruct([2;5;9],[1,5,10],rho,theta);
