A method for determining sucrose concentration in honey. The method includes preparing a sample of honey, stimulating the sample by emitting a first laser beam on the sample in a first stimulation direction, detecting a fluorescence spectrum from a first fluorescence emission emitted from the sample in a first detection direction, detecting a first pair of fluorescence peaks and a second pair of peak wavelengths in the fluorescence spectrum, and determining a sucrose concentration based on one of the first pair and the second pair utilizing a database. The database includes a plurality of predetermined sucrose concentrations associated with the first pair or the second pair.

A method for optical imaging based on spectral shift assessment. The method includes generating a sample by mixing an object with a fluorophore, stimulating the sample by emitting a laser beam, extracting a plurality of fluorescence spectra from a plurality of fluorescence emissions emitted from the sample, detecting a plurality of fluorescence peaks and a plurality of peak wavelengths in the plurality of fluorescence spectra, extracting a plurality of fluorophore concentrations from a database, and generating a concentration image. The plurality of peak wavelengths are detected by detecting a respective peak wavelength of the plurality of peak wavelengths. Each of the plurality of fluorophore concentrations is associated with a respective peak wavelength of the plurality of peak wavelengths. The concentration image includes a first plurality of pixels. The concentration image is generated based on a respective fluorophore concentration of the plurality of fluorophore concentrations.
