... aaand its Fourier transform 💥 #Braggyourpattern #crystallography #totalscattering #Fouriertransform
Fast Fourier Transform of the cited pattern, showing a network of diagonal streaks and an ensemble of tiny squares of Bragg-looking peaks arranged in square superstructures.

Here it is, pattern nr. 54 #crystallography #totalscattering #Fouriertransform #sciart #Braggyourpattern #specialdefects
Fourier transform of the quoted pattern, showing plenty of dots clustered in a square grid, with systematically weaker spots in the centre of squares.

Fouriertransform och Lagrangepunkt klingar så cool och avancerat medan Hilbertrummet mer låter som en yta man ska komma ihåg att dammsuga.

Att sitta i regeringen utan att känna till Sveriges grundlagar är ungefär lika sjukt som att sitta på Bluesky utan att kunna linjär algebra eller en snabb Fouriertransform.

Sjukt cringe ju men okej (◕‿◕)♡

A little bronze gnome holding the Oxford diffraction logo in his hand, in front of his face. In front of him, a beautiful blue pattern appears on a dark screen: the Fourier transform (diffraction pattern) of the logo!

In case someone was wondering about the origin of those frequences... 😌 I admit this is pretty challenging to decipher in terms of real-space to reciprocal-space relationship, without knowing know how it is made. #FourierTransform #Crystallography #Braggyourpattern
An aperiodic tiling formed by the intersection of two square tilings of squares, one tilted by 43° with respect to the other. Many shapes are visible, diamonds, triangles, irregular octagons, and many other.

And here we have our Fourier transform nr. 58! As far as I'm concerned, perhaps the most enigmatic and unexpected spectrum so far... anyway, quite a spectacle! #BraggYourPattern #Fouriertransform #crystallography

As always, more on behance.net/specialdefects and instagram.com/specialdefects
A square divided in four squares, each containing strands of violet-and-blue light - some like rays, some like diffuse bands - separated by darker shady regions. Overall, these lights look like refractions coming from the centre of the image, which gets darker and darker in approaching the very middle.

... and its beautiful #Fouriertransform, completing #specialdefects pair nr. 55 👾 Those who got a little used to how the Fourier space works might guess (correctly) that this looks essentially like the FFT of a single 12-pointed star ✍️ #BraggYourPattern #TotalScattering #Crystallography
Fourier transform of the quoted image. Bright strands raidating from the centre, oscillating in intensity along the lines, and bumping on the image sides. The colour scheme is created to show these lines as sparks from a firework, with sharp white-yellow-brown gradients.

My fellow #FourierTransform enthusiasts, here's a new entry in my collection ready for you, nr. 56! The real-space picture is an intersection of two tilings of squares, one tilted by 43°. Moiré pattern? Definitely related 💯

As always, you can find the high-res pair at behance.net/specialdefects
A collection of bright yellow spots starts from the centre of the picture, from the strongest, central one. Clearly not periodically arranged, they have a point-symmetry evident since 4 equally spaced lines of stronger spots irradiate from the centre of the image. Between them, additional smaller spots form geometrical patterns vaguely resembling the fourier transform of an aperiodic crystal. The background colour alternate dark blue and soft teal, whose calm feeling contrasts the energy present in the bright yellow spots, looking like tiny fireflies.

New castor wheels on piano. They required wood filler and shims. Now to replace the frayed wire that powers the chip that processes the audio. Oh, and I’ll need help lifting this back on its feet.

The Fourier transform in analytical science - Nature Reviews Methods Primers
The Fourier transform is a mathematical tool for analysing signals that vary in space or time via a transform into the frequency domain. This Primer explores how the Fourier transform is used in analytical science, particularly for spectroscopic data, with an overview of theoretical and experimental considerations.

And finally, the 8th #crystallography teaching set is online ✅ The series is now extended to 'shapes', 'molecules' (below), and 'creatures'... but be aware: by the time you reach the last section things get a little #nerdy 👾 -- #totalscattering #Fouriertransform

A 7x7 grid of images showing the effect of phases and amplitudes on the reconstruction of a picture from its Fourier components. Every line has amplitude from the same figure, but phases from different ones, while the opposite is true for every column. The images on the diagonal show the original pictures used for the grid. These are representing black&white molecular structures of, in order, caffeine, capsaicin, cinnamaldehyde, methylene blue, sucrose, porphyrin, and glutamic acid.

Roar. For me it's common mistakes and misconceptions! For example, I've seen so many people taking only the real part of #FourierTransform when they meant to take modulus instead!

I'm implementing some new #FourierTiler functions for my powderdiffy friends; after all single crystal diffraction is just a highly-mono-oriented powder diffraction, isn't it... pity for that nice diffuse "scattering" though 🍃 #Crystallography #TotalScattering #FourierTransform #BraggYourPattern
Four different patterns calculated from a MOF-5 simulant tiling using Fourier Tiler. The four patterns are computed by considering a mosaic orientation spread of 0, 3, 10, 90 degrees. As a result, the pointy Bragg peaks smear into arcs, large lines, and eventually homogeneous circles, while the diffuse scattering features from missing cluster defects are not recognizable anymore, if not for a bright blob in the centre.
