In order to improve the efficiency and accuracy of the channel calibration

a full channel automatic calibration system is developed to investigate the 3D MOEMS optical switch array.Through the test of the calibration search process and the analysis of the search algorithm

this paper proposes a combined search method of fine search based on genetic algorithm and rough search based on hill search algorithm.Then

full-channel automatic calibration system is proposed based on a series of test experiments.Finally

the variation rule of the optimal voltage and the number of channels and rows are summed up in the test of the whole channel search scheme.The experimental results show that the full channel search scheme has higher feasibility and search efficiency than conventional methods.
