precise displacement
This dataset presents one-shot measurements of a multimode fiber subjected to displacement over a range of 18mm, with a fine resolution of 0.01mm. The data captures the intricate light patterns transmitted through the fiber at each displacement position, providing a detailed view of the fiber's behavior under varying conditions.

Because of the demand for seamless indoor and outdoor positioning of mass market applications, several simple and efficient pedestrian dead reckoning (PDR) systems have been introduced. However, the performance of PDR system would significantly decrease with the increase of recursion time, due to the influence of sensors and model error. This paper discusses the overview of pedestrian navigation system and the implementation of key techniques of PDR, then proposes an improved PDR system with precise displacement estimation based on time-differenced carrier phase (TDCP) technique.
