TL;DR: A spectrometer capable of measuring sample absorption spectra in the visible regime, based on a time-domain scanning Fourier transform (FT) approach, that exploits a compact common-mode passive interferometer that relies on the use of birefringent wedges.

TL;DR: The results pave the way to high-speed broadband vibrational imaging for materials science and biophotonics.

TL;DR: A high-performance hyperspectral camera based on the Fourier-transform approach, where the two delayed images are generated by the Translating-Wedge-Based Identical Pulses eNcoding System (TWINS), that generates high-contrast interferograms at the single-pixel level is introduced.

TL;DR: A compact, fast and versatile Fourier-transform spectrometer, combining absorption and excitation-emission fluorescence spectroscopy in the visible, generating phase-locked excitation pulse pairs via an inherently stable birefringent wedge-based common-path interferometer.

TL;DR: In this paper, a passive common-path interferometer was proposed to replace Michelson interferometers in the Fourier transform spectroscopy, which can be used even for short wavelengths (down to ∼200nm) without the need for any active control or position tracking.
