An automatic endoscope, called a rhizoscope, has been developed to study the growth of plant roots in the soil. Unlike conventional methods, this method is nondestructive for cultivated plants. This work has required the development of an original electro-optical sensor and an automated driving system. The rhizoscope is operated by a microcomputer. The root images are stored on floppy disk for off-line processing and analysis. Preliminary test results, obtained by simulation and in a greenhouse, are presented.
