Figure S4. Computational light-field renderings and 3D depth reconstructions of numeric cube targets by using the fully integrated NIR-ULFC without NIR bandpass filter. Each of numeric targets are located at 40 mm, 90 mm, and 180 mm from the NIR-LFC. a) Vertically shifted sub-aperture images with different viewing angles. The white dotted lines indicate the original position of numeric cube ‘3’ (center sub-aperture image), and the images on the left and right are obtained by changing the viewing angles up and down. b) Digital refocusing results of the targets, which focus on ‘1’ (left), ‘2’ (center), and ‘3’ (right), respectively. Asterisk symbols at each image indicate the focused point. c) Disparity map calculated by pixel-by-pixel cost volume filtering from the whole 27 x 27 sub-aperture images. d) 3D reconstruction of the targets after image warping by using a disparity map and a center sub-aperture image. The 2D image is warped on the disparity map. e) 3D depth map containing discrete depth information is calculated by using the disparity map obtained from c) and camera matrices, i.e., intrinsic parameter ([K ]) and extrinsic parameter ([R |t ]) from geometric calibration steps. The calculated z-axis depth for each numeric target is 44 mm, 97 mm, and 191 mm, respectively, similar to those of actual positions.
