A portable system and method for analyzing biological tissue samples and detecting analytes associated with tissue oxygenation using a conformal filter. A conformal filter, which may comprise a tunable filter, i
Previous probe designs are also inadequate because of the environmental sensitivity of the spectral filters that are employed in the devices. The Raman chemical imaging fiberscope design of the current invention relies on spectral filter technologies that are remarkably immune to temperature and humidity...
and there being an optical filter interposed between the second detector and the identified regions and; a computer processor operably linked to the second detector for restricting assessment of Raman-shifted scattered radiation to the identified regions and for correlating Raman-shifted radiation scattere...
Several Raman chemical imaging technologies have evolved that compete with widefield tunable filter-based RCI. These techniques include point scanning RCI, line imaging RCI, RCI using interference filters, Fourier-transform interferometry, Hadamard-transform scanning and FAST technology. Point scanning involv...

The combined properties of these elements (i.e., the light source, the filter, grating, or other mechanism used to distinguish Raman scattered light by wavelength) define the spectral resolution of the Raman signal detection system. The known relationships of these elements enable the skilled ...
filter based technologies. Software, hardware, and/or a combination of software and hardware may be used to extract the spatial/spectral information to reconstruct data. Furthermore, FAST is a rugged technology that operates over an extensive spectral range from UV to IR. Therefore, the system ...
