To evaluate and optimize the flicker visibility in solid-state 3D volumetric display, a interlaced scanning refresh method of shutter array is proposed. Frequency domain energy distribution of the imaging light signal in different scanning modes is analyzed through Fourier transformation. Based on the temporal contrast sensitivity function weighted amplitude(CSWA) model, the method of temporal contrast sensitivity function weighted amplitude contrast(CSWC) is proposed. Meanwhile, Pearson correlation coefficient between two visual perception experiment results and the estimation result of CSWC model is -0.99, which shows that the proposed method could reduce flicker visibility, and the proposed CSWC evaluation model realizes objective evaluation of the flicker in solid-state 3D volumetric display. The result can guide and facilitate the flicker optimization in 3D display based on the depth-fused principle and the improvement of visual comfort.
