A Light Power And Wavelength Synchrometer Based On Silicon Color Sensor With Double Junction

This thesis analyze the error that came from method of calculate light power when using dual junction silicon color sensor as a power meter sensor of light. In older to decrease the error, a new compensated method was provided and proved. The method simulates the sensor's spectral response curve and all kinds of input spectral with polynomials by the Mathematica4 software. After computed, the result shows that the compensated method can decrease the error of power clearly. Based on this method, a news design of light power and wavelength synchrometer system using dual junction silicon color sensor was provided. PC is used as assistant processor and memorizer, it make the meter measure synchronously, real-timely and automaticallyThis thesis consists of six aspects:1. Where is the error come from when using dual junction silicon color sensor to measure polychromatic light's power.2. The origin of compensated method and how to use it with mathematical method.3. Computing the result of using compensated method by Mathematica44. The hardware of light power and wavelength synchrometer system using dual junction silicon color sensor5. Software design of single chip processor6. Software design of PCFor the PC have powerful computed speed, huge memorizer and plenty application software, system can be expended into many customized model conveniently when using PC as assistant processor. For example, set a safe rang and automatically give an alarm, automatically measure and memorize once per setting time, far away measurement and driver other Actuators or processor. So the light power and wavelength synchrometer system using dual junction silicon color sensor has a hopeful future.
