Happy Birthday 🎂 ThePythonCodingBook.com
You're turning 1 🕯️ in a few days' time.
I'm still shocked how almost 20,000 people visit every month just from organic traffic.
A number of posts have done extremely well.
Here are the top five:

Let's fork this thread since people seem to be as fascinated by this topic as I am…
This process happens in nature. Any lens (a camera lens, the eye) 'calculates' the #FourierTransform of the object being imaged.

The Fourier Transform coincides with the plane of the lens. So small lenses cut out the higher spatial frequencies that are furthest from the centre.
Therefore, these higher frequencies do not go through the lens and they're lost…

Therefore, these higher frequencies do not go through the lens and they're lost…

So when the remaining frequencies are recombined at the image plane (say the back of the camera or the back of the eye), the terms that are needed for the fine detail are not there…
The image is blurred.
This is diffraction.

What's an image made of?
There are many correct answers.
But the most fascinating one is: << sines & cosines >>

*Any* image can be reconstructed from a series of sinusoidal gratings.
A sinusoidal grating looks like this…

A sinusoidal grating looks like this…
#sinusoidal #grating
It’s called a sinusoidal grating because the grayscale values vary according to the sine function.
If you plot the values along a horizontal line of the grating, you’ll get a plot of a sine function
