Paper Abstract

The Optical capability of visible light transmittance is studied on this paper. The system is based on the principle of cross-correlation detection, and measure the transmittance of visible light Optical system though the way of dual-channels, compare to the previous way, eliminate the error of measuring many times, and restrain the noise signal more effectively. Moreover, the whole system can work on the conditions of light field. And monitoring and dealing with the result in real-time. The testing accuracy reaches 1%.
