Paper Abstract

This paper mainly introduces the basic principle, construction, technology and signal process circuit of the developing three primary colors semi-conductor color sensor. This kind of sensor not only possesses the characteristic of a small volume, light weight, fast colorimetric determination, lower power consumption and flexibility, it also can be applied to dynamic situations. And its automatic control can be conveniently realized. The color-sensitive element in sensor is also the chiefly selected product in intelligent and miniaturized colorimetric equipment. Because the color sensitivity element we adopted possesses the structure of three different color sensitivity PN knots which is related to the waves of three primary colors, the sensor possesses the function of self color filtration. Because we don't use a filter, the cost is low, and because we don't use the filtration structure with a filter, the high integration is conveniently achieved. The range of colorimetric determination of the equipment is wide, and it can also be applied to the situation where direct determination is not available, such as in the situation of optical fiber color detection.
