LIFLET有一个菲涅耳透镜、一个GRIN透镜阵列、一个IEEE1394 XGA相机和一台PC。图2显示了系统的示意图。菲涅尔透镜通过控制景深，帮助GRIN透镜阵列获得更大范围的场景。GRIN透镜阵列产生数千个基本图像(例如，20×20像素的50×40图像)。PC从IEEE1394 XGA相机捕获的元素图像合成自由视点图像。
LIFLET has a Fresnel lens, a GRIN lens-array, an IEEE1394 XGA camera, and a PC. Figure 2 illustrates a diagram of the system. The Fresnel lens helps the GRIN lens-array to pick up wider range of a scene by controlling the depth of field. The GRIN lens-array produces thousands of elemental images (for instance, 50×40 images of 20×20 pixels). The PC synthesizes free-viewpoint images from the elemental images captured by the IEEE1394 XGA camera.
