Portable Video Imager for Detecting Stress in Plants

A portable instrument can generate video images indicative of physiological stress in plants. The instrument exploits the known relationships among physiological stress in plants, loss of chlorophyll, and changes in spectral reflectance. The instrument acquires multispectral video images of a scene that contains plants, digitizes the images, and processes the image data to generate a new image that maps chlorophyll loss in the scene.
