Abstract: A high-dynamic-range hybrid solid-state lidar system, which is based on a transponder array module, includes a transmitting system, a transceiver integrated optical system, a one-dimensional scanning device, a detecting system, and an information processing system. An information processing control circuit and a gain control module increase a total amplification factor, in a single timing period, of a gain circuit over time, thereby alleviating an echo signal intensity distortion, and expanding a dynamic ranging range. The system uses the one-dimensional scanning device and the transceiver integrated optical system composed of a circulator, a lens set, and an optical fiber array, so that the optical system is separated from an avalanche photo diode (APD) detector, and focusing is not required. A temperature of a linear APD array is monitored in the detecting system to adjust a reverse bias voltage of an APD correspondingly and alleviate unstable gain caused by a temperature change.

Abstract: Training at the proper level of effort is important for athletes whose objective is to achieve the best results in the least time. In running, for example, pace is often monitored. However, pace alone does not reveal specific issues with regard to running form, efficiency, or technique, much less inform how training should be modified to improve performance or fitness.
