Exploration of agricultural ecosystem monitoring technology based on laser speckle contrast imaging

To monitor key parameters in agricultural ecosystems, laser speckle contrast imaging technology is utilized to analyze plant growth dynamics and soil moisture changes. Through quantitative speckle images, the micro-movements of plant leaves and their physiological activities, as well as changes in soil speckle intensity under different humidity levels, are revealed. The results show that this technology can accurately reflect micro-changes within the ecosystem, providing scientific support for ecological management and optimization decisions.
