Paper Abstract

Vegetation stress detection is of great importance to many agricultural and ecological studies. Vegetation water stress is commonly encountered in many areas. The accurate detection of water stress may enable more efficient use of limited water resource. Plant leaf water content is also one of the primary factors indicating vegetation health condition. In this study, a polarized laser at 532-nm was used to study water stress from plant leaves. Polarimetric measurements of the backscattered light were conducted. Preliminary study indicates that depolarization ratio is a good indicator of water stress in the studied case. In addition, an overall increasing trend of depolarization ratio under water stress condition was also observed.
