“…For example, the work of Lee et al [ 19 ] proposes a light-field-based 3D HUD that uses eye-tracking. Furthermore, there are immersive HMIs in the scientific literature that show promise for the automotive context, such as the light field prototype of Duarte et al [ 22 ], yet are not designed particularly for the investigated utilization.…”

“…Related research efforts study the hardware-in-the-loop simulation of autonomous vehicles [ 12 ], light field imaging for autonomous underwater vehicles (AUVs) [ 13 , 14 ], zero-latency motion visualization [ 15 ], and AR [ 16 , 17 , 18 , 19 , 20 ] automotive head-up displays (HUDs). Light field HUDs and windshields (or windscreens) are addressed by several works [ 21 , 22 , 23 , 24 , 25 , 26 ]; however, none of them study V2X sensor data. For example, the recent work by Murugan et al [ 27 ] focused solely on information about the autonomous vehicle in which the AR HUD was situated.…”

The practical usage of V2X communication protocols started emerging in recent years. Data built on sensor information are displayed via onboard units and smart devices. However, perceptually obtaining such data may be counterproductive in terms of visual attention, particularly in the case of safety-related applications. Using the windshield as a display may solve this issue, but switching between 2D information and the 3D reality of traffic may introduce issues of its own. To overcome such difficulties, automotive light field visualization is introduced. In this paper, we investigate the visualization of V2X communication protocols and use cases via projection-based light field technology. Our work is motivated by the abundance of V2X sensor data, the low latency of V2X data transfer, the availability of automotive light field prototypes, the prevalent dominance of non-autonomous and non-remote driving, and the lack of V2X-based light field solutions. As our primary contributions, we provide a comprehensive technological review of light field and V2X communication, a set of recommendations for design and implementation, an extensive discussion and implication analysis, the exploration of utilization based on standardized protocols, and use-case-specific considerations.

The testing of astigmatism and field curvature of an optical system with light-field imaging is proposed. The method consists in measuring the depth map, obtained with a plenoptic camera, of the image of a test pattern formed by the optical system. To demonstrate the accuracy of the method, the virtual image formed by a plano-convex lens was tested. The resulting depth map was compared with the sagittal and tangential foci distances calculated with the Coddington theory. The proposed method could be applied to the quality testing of ocular optics, including eyeglasses, eyepieces, virtual reality goggles, and augmented reality devices.
