Detection of mass 31,830 ions with an external ion source Fourier transform mass spectrometer.

Compact Fourier-transform volume holographic spectrometer for diffuse source spectroscopy.

We present a new idea for diffuse source spectroscopy using a Fourier-transform volume holographic spectrometer formed by a Fourier-transform lens, a volume hologram, and a CCD. We show that this spectrometer can operate well under spatially incoherent light illumination. Furthermore, this spectrometer is less bulky, less sensitive to input alignment, and potentially more appropriate for implem...

Birefringent Fourier-transform imaging spectrometer.

Fourier-transform imaging spectrometers offer important advantages over other spectral imaging modalities, such as, a wider free spectral range, higher spectral resolutions and, in low-photon-flux conditions, higher signal-to-noise ratios can be achieved. Unfortunately, for application in harsh environments, deployment of Fourier-transform instruments based on traditional moving-mirror interfer...

Design and performance of an atmospheric pressure ion mobility Fourier transform ion cyclotron resonance mass spectrometer.

This manuscript presents our initial results and development of a novel hybrid instrument that combines atmospheric pressure ion mobility spectrometry (AP-IMS) with Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS). Our preliminary results obtained from atmospheric pressure mobility separation of peptide mixtures combined with high-resolution FTICR mass analysis are demonst...

Slow-light fourier transform interferometer.

We describe a new type of Fourier transform (FT) interferometer in which the tunable optical delay between the two arms is realized by using a continuously variable slow-light medium instead of a moving arm as in a conventional setup. The spectral resolution of such a FT interferometer exceeds that of a conventional setup of comparable size by a factor equal to the maximum group index of the sl...
