Abstract:
Laser-induced chlorophyll fluorescence (LICF) emission spectra of leaves of some tropical plants were measured using a compact fiber-optic fluorosensor with a continuous-wave blue diode laser as exciting source and an integrated digital spectrometer. Different chlorophyll-fluorescence signatures of light-green, fully-green, and yellow leaves were monitored at room temperature. Deconvolution procedure was used to determine fluorescence band position and width. Calibration of the fluorescence ratio F690/F730 relative to the 404 nm excitation is done from the curve-fitted parameter.

Photons
A photon is a discrete electromagnetic particle or bundle of energy. Photons are characterized by their frequency, wavelength, and amplitude, similar to the properties of a wave. Waves with higher frequencies transmit more energy and have shorter wavelengths than longer wavelengths that transmit less...
