A Device to Quantify Leaf Chlorophyll Content

Summary

Researchers at Purdue University developed a method and system for spectrometer-less hyperspectral imaging that can map out detailed spatial distribution of chlorophyll content, which is a key trait for determining the 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. In addition, this imaging platform can be integrated into a compact, inexpensive, portable imager for plant biologists and ecophysiologists.
