Abstract

Laser-induced fluorescence (LIF) is emitted from leaf pigments irradiated with laser. LIF contains lots of information on living plants, so LIF spectroscopy, also known as the LIF technique, is a powerful tool for plant investigation. This paper mainly describes 1) the information that is obtained by plant LIF experiments with a focus on plant physiological information, and 2) practical field applications of the LIF technique, especially to agriculture and forestry, together with a detailed description of equipment systems. Through several experimental results, the usefulness of the LIF technique is discussed as a field monitoring technique for plant investigations. Finally, the concepts of a "general hospital for plant diagnosis" and "optical farming for the agricultural industry" based on LIF information are proposed.
