Measurement and correction of the macrolens array's position error in integral imaging.

Abstract

The macrolens array is generally used in the large-format integral imaging display system, and the position error of the lens will affect the result of the integral imaging display. In this paper, the average value and variance of the distances from the distributed reconstructed points to their ideal points are used to measure the size of the position error, and the performance of the measurement methods is discussed. The one-to-one relationship of the pixels of the elemental image under the ideal case and the position error are analyzed, and the corresponding correction methods of these position errors are analyzed. Then the pixels are rearranged to compensate for the position error, thereby alleviating the influence of the microlens array's (MALA's) position error on the imaging quality, which is verified by theoretical simulation and experimental results.
