Abstract

We present a technique for monitoring alien substances in foods and blood vessels in the human body. A prototype of the system using near-infrared rays is developed, and its applicability to food is analyzed in detail. The system developed is basically composed of an optical source and a CMOS sensor. Some optical components adjusted at 850-nm band are also set in the system. The system can monitor organic alien substances intentionally added to foods and blood vessels. The clarity of the image increased with decreasing water content and homogeneous material density. The resolving power of the images was confirmed to be about 100 μm. This technique will be useful for our safety and health in our daily lives.
