Abstract: This paper proposes a tracking system that integrates visible-light positioning and pedestrian dead reckoning using a smartphone’s built-in ambient light sensor and inertial sensors. By ...

Abstract: We have demonstrated a CMOS image sensor (CIS) with nano-light pillars (NLPs), which is metasurface-like structures, on a 0.8 μm-pixel sensor to enhance quantum efficiency. By employing a ...
