Title: Optical Aberration Analysis of Light Field Displays: A Calibration Approach for Enhanced Performance [SD&A-344]

Abstract: Real-world optical aberrations in light field (LF) displays can significantly influence overall display performance. They not only degrade the quality of individual viewpoint images but also affect the depth perception when all viewpoint images are superimposed, as perceived by the observer. In this study, we employed an optical model representative of a near-eye, time-multiplexed LF display. We established a relationship between the image input and the resultant output on the observer's sensor, enabling us to calibrate the aberrations associated with both viewpoint locations and image deformities. By pre-adjusting the input elementary images using calibrated coefficients, the impact of these aberrations was compensated. Simulation results, using a practical LF model, indicated improved accuracy of focusing effects and an elevated observed Spatial Frequency Response (SFR) performance, showing that the proposed method effectively neutralized the effects of the discussed aberrations.
