Near-Infrared 3D Imaging with Upconversion Detection
He Zhang, Santosh Kumar, Yong Meng Sua +2
We demonstrate a photon-sensitive, three-dimensional camera by active near-infrared illumination and fast time-of-flight gating. It uses pico-second pump pulses to selectively up-c…

Single-Photon Vibrometry
Patrick Rehain, Jeevanandha Ramanathan, Yong Meng Sua +3
We propose and demonstrate a single-photon sensitive technique for optical vibrometry. It uses high speed photon counting to sample the modulated backscattering from a vibrating ta…
