Fourier multispectral 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...

Fourier Multispectral Imaging: Measuring Spectra, One Sinusoid at a Time

Multispectral fluorescence imaging.

Multispectral fluorescence imaging (MSFI) is a rapidly growing field with broad applications in both preclinical and clinical settings. Application of this novel technology in small-animal imaging and microscopy produces enhanced sensitivity and reliable quantification and resolves multiple simultaneous signals. MSFI flow cytometry can quantify multiple fluorescent parameters with morphologic o...

CIC@20: Multispectral Imaging

A variety of multi-spectral imaging methods are discussed for acquiring spectral information from a scene. We first review conventional multispectral imaging approach. The conventional imaging systems are mostly constructed by multi-band imaging devices with different filtration mechanism at the sensor side under passive illumination. We show some imaging devices, estimation algorithms, and app...

Multispectral Imaging in Multimedia

An application of multispectral imaging in multimedia is presented. We describe a system for the acquisition of multispectral images using a CCD camera with carefully selected optical filters. We further discuss how the surface spectral reflectance of the imaged objects may be reconstructed from the camera response. We then present an application where the acquired multispectral images are used...
