摘要：

We proposed a resolution-enhanced integral imaging (II) based holographic stereogram (HS) using the moving array lenslet technique (MALT). The HS can be generated fast by Fourier transforming the elemental images of II into hogels. However, the low sampling rate of II is inherited in HS. The MALT was introduced to increase the sampling rate of II-based HS. Multiple elemental image array sequences are captured with MALT and transformed to the corresponding HS sequences. All the HS sequences are shifted depending on the movement of the lens array and added together to synthesize the HS with a high sampling rate. The synthesized HS can reconstruct the 3D image with the combined light fields of all the HS sequences. The 3D image quality improvement was verified in numerical and optical reconstruction. Superior to the MALT in II, this method does not need the time-multiplexing technique in the display stage because different HS sequences are displayed in one hologram pattern simultaneously.
