When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording the diffraction patterns formed by shining a laser beam through it. At the ...

Over at Quanta Magazine [Shalma Wegsman] asks What Is the Fourier Transform? [Shalma] begins by telling you a little about Joseph Fourier, the French mathematician with an interest in heat propagation ...

Morrison Heights Baptist Church has a refreshingly current take underlying its traditional services. Its otherwise conventional worship style, complete with an instrumental mixture of traditional ...

This implements MATLAB + CUDA programming for the acceleration of Fourier ptychographic microscopy (FPM) reconstruction. FPM's forward and backward progress are all calculated purely by CUDA in ...

The inverse transform can create a time-domain waveform where no waveform has been before. In part 2 of this series, we used the discrete Fourier transform to convert a waveform from the time domain ...

Fourier transform is a key method for analyzing signals in both time and frequency domains. The FFT is a computational algorithm that efficiently computes the discrete Fourier transform (DFT) and its ...

Abstract: The hyperbolic fractional Fourier transform (HFrFT) as a generalized form of the fractional Fourier trans-form (FrFT) based on complex transform orders is introduced. This paper defines the ...
