The Hardware System Design of Smart Color Mark Sensor

Abstract

In this paper, the principle and new structure of the smart color mark sensor is presented. Especialy, the design of the smart color mark sensor's hardware system based on the photoelectric measurement is described in detail, including coaxial optical system, microcontroller system, some special hardware circuits and application of synchronous and coherent detectionin in the smart color mark sensor as a Intelligent optoelectronic device. In the end, the test results of sensitivity, response speed, output characteristics, stability and so on are presented.
