We demonstrate photon-counting single-pixel imaging in the ultraviolet region. Toward this target, we develop a high-performance compact single-photon detector based on 4H-SiC avalanche diode (SPAD), where tailored readout circuit with active hold-off time is designed to restrain noise and operate SPAD free-running mode. use structured illumination reconstruct 192 × compressed images at 4 fps f...

There has recently been a keen interest in developing Light Detection and Ranging (LiDAR) systems using Single Photon Avalanche Diode (SPAD) sensors. This led to variety of implementations pixel combining techniques Time Digital Converter (TDC) architectures for such paper presents comparison these approaches demonstrates technique capable extending the range LiDAR with improved resilience back...

Early signs of intestinal cancer may be detected through variations in tissue autofluorescence (AF), however current endoscope-based AF systems are unable to inspect the small intestine. This thesis describes the design, fabrication, implantation, testing and packaging of a wireless pill capable of detecting the autofluorescence from cancerous cells, and able to reach parts of the gastrointesti...
