US Patent 7715013 Optical system for plant characterization

A system is provided to monitor targeted pest populations, disease, presence of transgenic and non-transgenic plants, or targeted pest population in a transgenic crop using remote imagery to discern differences in crops along with pest infestation in all crop varieties. The system relies on the fact that plant leaves are known to change color based on stress, herbivory, and other environmental factors. The system provides a special camera that can see reflected light energy across the visible and near infrared (about 400-1000 nm) to identify these effects.
