Experimental assessment of a 3-D plenoptic endoscopic imaging system

An endoscopic imaging system using a plenoptic technique to reconstruct 3-D information is demonstrated and analyzed in this Letter. The proposed setup integrates a clinical surgical endoscope with a plenoptic camera to achieve a depth accuracy error of about 1 mm and a precision error of about 2 mm, within a 25 mm×25 mm field of view, operating at 11 frames per second.
Auxiliary resonant scanner to increase the scanning capability of coarse integral holographic displays

This Letter proposes a scanned holographic display system that takes the advantage of a high-speed resonant scanner to augment a galvanometer and hence improves the opto-mechanical information distribution capabilities, thereby potentially achieving an increased image size and enlarged viewing angles. 
Upstream dispersion management of 25 Gb/s duobinary and PAM-4 signals to support 0–40 km differential reach

We extensively discuss 25 Gb/s per wavelength capacity in both IEEE and ITU-T standardization to support the increasing bandwidth requirement. In this Letter, we propose to use the optical dispersion compensation technique in an optical line terminal (OLT) combined with a bandwidth-limited electro-absorption modulated laser in an optical network unit to achieve 25 Gb/s capacity for the upstream li...
Three-dimensional imaging lidar system based on high speed pseudorandom modulation and photon counting

High speed pseudorandom modulation and photon counting techniques are applied to a three-dimensional imaging lidar system. The specific structure and working principle of the lidar system is described. The actual detector efficiency of a single-photon detector in an imaging system is discussed, and the result shows that a variety of reasons lead to the decrease in detection efficiency. A series of...
