Laser-induced fluorescence spectra of some green plants commonly found in the Philippines

Abstract

Laboratory and aerial remote experiments using the laser-induced fluorescence (LIF) properties of plants have been conducted to detect vegetation, plant stress, and to identify plant groups or plant species. An investigation was made on the feasibility of using laser-induced fluorescence as a technique to identify Philippine green plants. A 337.1 nm output nitrogen laser was used to induce fluorescence. The measured LIF spectra of freshly cut leaves of bamboo, coconut, palm, papaya, and starapple are presented. Experimental results and analysis of the LIF spectra are discussed.
