Hi everyone,
I have this Matlab code :
function PH = testing
close all;
x = [0:1e-3:10-1e-3];
ph = -(x-5).^2;
y = exp(-(x-5).^2./(0.2^2)).*exp(i*2*pi*ph);
Y = fft(y);
Y = fftshift(Y);
PH = angle(Y);
X = (x(2) - x(1))^-1*linspace(0,1,length(x));
figure
plot(x,ph);
figure...
Hi everyone,
I was working recently with a Michelson interferometer and measured the spectrum of the two pulses and see how the fringe spacing of the spectrum change as I change the position of one of the two mirrors in the interferometer, that is the time interval between the two pulses.
I...
