Conventional lens-enhanced aerial imaging by retro-reflection (LeAIRR) requires the displayed image to be magnified onto the retro-reflector to form a high-resolution aerial image, which requires a retro-reflector with an area larger than that of the displayed image. Consequently, enlarging the aerial image increases the size and cost of the optical system. To address this issue, we propose a large-screen LeAIRR system that reduces the required retro-reflector area by taking advantage of the larger pixel pitch of large-screen displays and demagnifying the displayed image onto the retro-reflector while maintaining pixel-pitch matching. Next the demagnified image is magnified by a Fresnel lens, thereby maintaining the size of the aerial image. Using the same-sized retro-reflector, the proposed system formed an aerial image approximately 2.7 times larger than that formed by conventional AIRR. |
