It is now possible to calculate the Fourier transform of an image on your smartphone, thanks to a new app developed by two nanophotonics researchers in The Netherlands. “2D-Fourier” is ...

Following 2D Fourier Transform, the ensuing spectrum has a reduced diagonal signal, at a price to the signal-to-noise ratio. But the decreased diagonal signals make it easier to distinguish close ...

To form an image of the sky, one takes the inverse 2D Fourier Transform of the correlator output. However, for virtually all radio interferometers, the distribution of projected baselines on the ...

This article focuses on the use of electron microscopy paired with fast Fourier transform (FFT-EM), its advantages and limitations, alternative methods, and recent studies involving this method.

Bruker BioSpin announces the new Fourier 300, easy-to-use 300 MHz high-resolution spectrometer that brings Fourier transform (FT) Nuclear Magnetic Resonance (NMR) spectroscopy within every chemist's ...

An interesting aspect of time-varying waveforms is that by using a trick called a Fourier Transform (FT), they can be represented as the sum of their underlying frequencies. This mathematical ...

Since the formulae in the convolution method involve only summations over one variable at a time, while a two-dimensional reconstruction with the Fourier transform technique requires double summations ...
