FTIR-7600 is a single-beam Fourier-transform infrared spectrometer with fast scan speed and high accuracy. This instrument is operated by a PC with user friendly software and a comprehensive manual.
Deep learning surrogate models have shown promise in solving partial differential equations (PDEs). Among them, the Fourier neural operator (FNO) achieves good accuracy, and is significantly faster ...
The current frequency-domain imaging algorithm is not suitable for nonuniformly sampled data. This article proposes a method based on nonuniform fast Fourier transform (NUFFT) and modified ...
