Paper Abstract
This paper presents an optical system for performing excitation resolved imaging of fluorescent
dyes, tissue phantoms and ex vivo tissues. The excitation source was a supercontinuum generated in
a highly nonlinear fibre, spectrally filtered using dispersive optics and a movable slit or digital
micromirror device. This allowed excitation with multiple spectra, which may be chosen to
optimize the fluorescence yield from a particular fluorophore, or to maximize discrimination
between multiple labels. As an initial validation, the analysis of fluorescent dye solutions
embedded in collagen gels in the presence of scatterers and absorbers by using fixed reference
isomap (FR-IsoMap) is presented, followed by initial evaluation with human lung bronchial tissue.
The proposed system has potential applications for in vivo fluorescence endoscopy of cancerous
tissues through excitation spectral selection and analysis with FR-IsoMap.
