Fourier-correlation imaging

Fourier multispectral imaging.

Current multispectral imaging systems use narrowband filters to capture the spectral content of a scene, which necessitates different filters to be designed for each application. In this paper, we demonstrate the concept of Fourier multispectral imaging which uses filters with sinusoidally varying transmittance. We designed and built these filters employing a single-cavity resonance, and made s...

Measurement of the dynamic structure function of fluorescently labeled complex fluids by fourier imaging correlation spectroscopy

Wave-number-resolved time-correlation functions of density fluctuations are determined from purely incoherent fluorescence signals using a new method, Fourier imaging correlation spectroscopy (FICS). We demonstrate the application of FICS to chemical and biological samples with ultrahigh signal sensitivity and time resolution superior to direct imaging methods. We outline the theory that establ...

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...
