【Abstract】 The main work is to research high resolution light scanning two-dimension pH image sensor based on EIS structure,and use this sensor measuring system to measure the two-dimension distribution of pH value of the solution. The structure of sensor chip and the system to realize the measure for pH value,the effects of measurement conditions on output photovoltage for the sensor are studied mainly.Based on all above work, the two-dimension distribution of the pH value of the solution is measured and the map of two-dimension pH distribution of the certain solution can be drawn in different gray levels.更多还原
