When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording ...

A talk, The Unreasonable Effectiveness of the Fourier Transform, was presented by [Joshua Wise] at Teardown 2025 in June last year. Click-through for the notes or check out the video below the break ...

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.

Abstract: This paper presents a novel analysis and optimization approach for quantized-analog (QA) amplifiers using the Fourier transform. Traditional linear approximations fail in QA systems, making ...

It has become evident to me that Python Scipy lacks a Fourier SERIES function! Unbelievable! I have made this for my peers in the Imperial College London Physics Department, I hope you find it useful ...

Abstract: Spherical measurement is a relatively important application in optical measurement. The interferogram obtained in spherical inspection usually consists of closed fringe patterns. Obtaining ...
