Publication number: 20180018537Abstract: Monitoring stress symptoms in plants is crucial to maximize crop productivity. Nondestructive imaging of physiological changes in plants has been intensively used as invaluable tools in the agricultural industry. However, this approach requires a bulky and expensive optical instrument for capturing full spectral information and often has intrinsic limitations for quantitative analyses. Disclosed herein are a method and system for spectrometerless hyperspectral imaging that can map out detailed spatial distribution of chlorophyll content, which is a key trait for physiological condition of plants. The combination of a handheld-type imaging system and a hyperspectral reconstruction algorithm offers the simplicity for instrumentation and operation avoiding the use of an imaging spectrograph. This imaging platform can be integrated into a compact, inexpensive, and portable imager for plant biologists and ecophysiologists.Type: ApplicationFiled: July 7, 2017Publication date: January 18, 2018Applicant: Purdue Research FoundationInventors: Young L.
