    Python Improving Fourier Transform Visualization in Python

    Hello, My name is Thibaut. I am looking to improve my code in python in order to have a better look a my Fourier transform. as you can see on the image, we barely see any detail of the peaks on the image. Also it's not centred. the zero order peak in on the corner, not in the centre. Any idea...

    Why Does Light Intensity Decrease with x^4 in 2D Fraunhofer Diffraction?

    Thanks, I have the array theorem under my eyes from the book "Optics" of Hecht. I think I will try to simulate the result of this convolution with python and I will show you what I obtained.

    Why Does Light Intensity Decrease with x^4 in 2D Fraunhofer Diffraction?

    It's a grid so I should have called it an ordered array of squared apertures. I would say that my laser beam covers 6 to 8 apertures on one side, so 36 to 64 holes in total. So it's not infinite. Thanks.

    Why Does Light Intensity Decrease with x^4 in 2D Fraunhofer Diffraction?

    I see what you mean now. It does make my point indeed. Thanks guys. I am looking for a way to express the intensity of the light as a function of x and y for a light passing through a squared grid. I find one equation for "diffraction by many slits". But I can't find any in the literature for a...

    Why Does Light Intensity Decrease with x^4 in 2D Fraunhofer Diffraction?

    Thank you guys. I will try again what you suggested blue but I fail to do so in the past. I don't understand the argument of Andy. What do you mean when you say "since the intensity is proportional to the field, the received intensity is proportional to x4"? Regards, Thibaut

    Why Does Light Intensity Decrease with x^4 in 2D Fraunhofer Diffraction?

    Hello, My name is Thibaut, I am a student in physics and I currently struggling with something that some of you might find obvious. I did an experiment with a laser 650nm passing through a 2D squared grid. The light interferes and diffracts and a photomultiplier collect only the central spot...
