An optical instrument was developed to detect various corn kernel defects by examining individual kernels based on the reflectance difference between sound and defective parts of the kernel surface. A low power helium-neon laser was used as the light source in the instrument. Broken, chipped-off, and starch-cracked kernels were detected with nearly 100 percent accuracy; while minor splits and cracks were detected with about 80 percent accuracy.
