With analysis of the principle of electro-optic mod-ulation, lithium niobate crystal is chosen to be a part of the half-wave voltage measurement system. Measurement of half-wave voltage is finished, theoretical calculation is done, and comparison of the calculation results and the ex-perimental results is completed. Factors influencing the half-wave voltage are analyzed, problems that should be taken care of in engineering application are mentioned.
