Range resolution refers to the ability of a laser rangefinder to distinguish between two objects that are located very close to one another. In more technical terms, it is the minimum detectable difference in distance between two targets that the device can effectively measure.
In the realm of hunting, each hunters would probably like to imagine themself as the sharpshooter, to make every shot count. But reality will knocks you down just as too much uncertain factors will fail your shooting, only tools that invented by science and technology can fulfill your dream.
Laser rangefinders and LiDAR are both laser-based distance sensors, but they serve very different roles in UAV surveying. A laser rangefinder is essentially a one-shot distance meter: it emits a focused laser pulse straight at a target and measures the time until the pulse returns, yielding a single distance measurement.
