Abstract

Abstract:

We quantitatively analyze the effect of the rotational misalignment between the display panel and the reconstruction lenslet array on the reconstructed image quality in the integral imaging system. First, the geometric optics and the ray tracing theory are utilized to build the rotational misalignment theoretical model based on the integral imaging principle by considering the optical axis translation motion and the pixel information dislocation. Then, the degradation of the image quality in the integral imaging system resulted from the rotational misalignment is simulated on the basis of the model mentioned above. Finally, the peak signal-to-noise ratio is introduced to quantitatively characterize the influence degree of the rotational misalignment on the reconstructed image quality, and the rotational misalignment limitations are given corresponding to the HVS observable threshold for different system parameters such as the lens pitch and the distance between the display panel and the reconstruction lenslet array. Research results will provide theoretical support for the parameters design and assembly of the display module in an integral imaging system.
