摘要

The true volumetric displays project a 3D image within a cube viewable from most of its sides thus providing the ultimate physiological depth cues for countless applications. The ultra-light and highly transparent aerogels may provide the best optical medium for these displays as they can be easily fabricated in the form of a large-volume, low-scattering bulk material. On the other hand, the semiconductor nanocrystals (quantum dots, QDs) are a remarkable fluorescent material with optical properties superior to those of conventional materials. QDs dispersed in aerogels hold a promise to become the most efficient display material for volumetric 3D displays. The true volumetric displays described in the literature are built around the concept of two beams exciting the fluorescent material in their intersection. However, the optical properties of QDs are quite different from these of the fluorescent materials proposed for intersecting-beams displays and it may not be feasible to build such displays using QDs. Instead, we are proposing the use of a single focused infrared laser beam to excite a nanostructured material for volumetric color displays consisting of QDs dispersed in a transparent silica aerogel matrix. Presented are the theory and modeling results proving the feasibility of this approach.
