A new algorithm performs Fourier transforms using a minimal number of samples. The fast Fourier transform, one of the most important algorithms of the 20th century, revolutionized signal processing.

The Fourier transform provides a perspective that an image consists of a weighted sum of harmonic 2D structured light patterns with different frequencies, as Supplementary Fig. 2 shows.

Conventional Fourier-transform infrared (FTIR) microspectroscopic systems are limited by an inevitable trade-off between spatial resolution, acquisition time, signal-to-noise ratio (SNR) and ...
