Automatic Measurement of Spectral Transmittance and Colour Contribution Index with Double Light Paths

本文叙述用双光路自动测量镜头的光谱透过率和彩色贡献指数的控制电路,及利用微机算出和打印光谱透过率和彩色贡献指数的程序流程图。

With the improvement of living standard and the development of science and technology, the requirements for the quality of the lens of colour camera is becoming higher. The spectral transmittance and CCI (colour contribution index) are two important quality indexes of the lens. The paper will describe the controlling circuit automatically measuring the spectral transmittance and CCI of the lens with double light paths, and flow chart calculating and printing the spectral transmittance and CCI by means of microcomputer.
