  • Distance measuring device and distance measuring method thereof
    Patent number: 10101451
    Abstract: In an embodiment, a distance measuring device comprises an absolute distance measuring module, a tracking module, a two-axis rotating mechanism and a signal controlling and processing module to track an object and measure a distance between the distance measuring device and the object. The absolute distance measuring module measures an absolute distance between the distance measuring device and the object. The absolute distance measuring module and the tracking module are combined by using a dichroic beam splitter, and then all of them are further disposed in the two-axis rotating mechanism. When the object moves, a tracking optical path changes accordingly. A quadrant photodetector of the absolute distance measuring module detects the changes to avoid the distance measuring optical path being interrupted, and generates and transmits the signal to the signal controlling and processing module for controlling the two-axis rotating mechanism to rotate, thereby tracking the object.
