Measurement and analysis on the accommodation responses to real-mode, virtual-mode, and focused-mode integral imaging display

Integral imaging has three display modes including real mode, virtual mode, and focused mode, and each mode has unique display characteristics. In this paper, the accommodation responses to the three-dimensional (3-D) targets reconstructed by each mode of the integral imaging display were measured and statistically analyzed. Through the least square method, standard deviation analysis, and t-test analysis, we found that the accommodation responses to the 3-D target reconstructed by the focused mode was more similar to that of the real target on the same depth position. Moreover, the closer to the central depth plane was, the steadier accommodation response 3-D targets could provide. These statistical analysis results are helpful to the design of integral imaging display device.
