摘要： To improve the distance measurement accuracy in a light receiving element that performs distance measurement on the basis of a light reception timing of reflected light. A charging section (330) causes a constant current to flow between any one terminal of a cathode and an anode of an avalanche photodiode (340) and a predetermined voltage. A source of a source follower transistor (320) is connected to the one terminal of the avalanche photodiode (340). A logic gate (350) outputs an output signal on the basis of a comparison result between a voltage of the one terminal of the avalanche photodiode (340) and a predetermined reference voltage. A source follower cut-off switch (310) opens and closes a path between a drain of the source follower transistor (320) and the predetermined voltage on the basis of the output signal.

摘要： A method implemented in a processing unit controlling a surveying instrument is provided. The method comprises obtaining a first set of data from optical tracking of a target with the surveying instrument, and identifying from the first set of data a dependence over time of at least one parameter representative of movements of the target. The method further comprises receiving a second set of data from a sensor unit via a communication channel, the second set of data including information about the at least one parameter over time, and determining whether a movement pattern for the optically tracked target as defined by the dependence over time of the at least one parameter is the same as, or deviates by a predetermined interval from, a movement pattern as defined by the dependence over time of the at least one parameter obtained from the second set of data.

摘要： Embodiments describe optical imagers that include one or more micro-optic components. Some imagers can be passive imagers that include a light detection system for receiving ambient light from a field. Some imagers can be active imagers that include a light emission system in addition to the light detection system. The light emission system can be configured to emit light into the field such that emitted light is reflected off surfaces of an object in the field and received by the light detection system. In some embodiments, the light detection system and/or the light emission system includes micro-optic components for improving operational performance.
