Abstract

A novel fiber-optic-based method for simultaneous time- and wavelength-resolved fluorescence spectroscopy for the rapid diagnosis of diseased tissue is demonstrated. By combining multiple bandpass and dichroic filters (405/40, 460/50, and 550/50) with different lengths of optical fiber (1, 10, and 19 m ) acting as an optical delay this system enables the near real-time acquisition and characterization of time-resolved fluorescence spectra using a single detector and excitation input. The recording of multiple fluorescence response pulses at selected wavelengths can be completed in hundreds of nanoseconds, which provides the capability of a real-time characterization of biological systems.
