Based on LAPS, the high resolution optical scanning two-dimensional pH image sensor and its measuring system are studied. The influence of sensor material and testing conditions on the sensor output voltage is studied emphatically and the optimization parameters are given. On this basis, the two-dimensional pH value of the solution was measured, and the two-dimensional distribution of the pH value of the solution was given.
