在平视配置下工作的透明光场3D显示器正在展出。该显示系统仅由商用投影仪和全息屏幕组成，并基于积分成像原理工作。全息屏是一种数字制造的体全息图，其功能相当于微凹面镜阵列。该屏幕还嵌入了其他光学功能，这有助于消除大量的光学元件。这大大简化了系统，使其更接近消费者市场。成功再现了20cm × 10cm × 5cm（深度）的彩色3D场景，可以用肉眼看到，视角为10度。
A see-through light-field 3D display that works in head-up configuration is being presented. The display system consists of only a commercial projector and a holographic screen and works on the principle of Integral Imaging. The holographic screen is a volume hologram that is digitally fabricated, which functions as a micro concave- mirror array. The screen also has other optical functions embedded that helps to eliminate the bulk of optical components needed otherwise. This significantly simplifies the system, there by taking it closer to the consumer market. A color 3D scene of size 20cm x 10cm x 5cm (depth) has been successfully reproduced and can be seen through naked eye for a viewing angle of 10-degrees.
