Abstract
A distance measuring device of the present disclosure is a device measuring a distance to a target, and includes: a near-infrared laser optical system generating a near-infrared laser pulse having a predetermined NAR (Non-Ambiguity Range) value to be emitted toward a target and receiving the near-infrared laser pulse reflected from the target to be converted into a near-infrared electrical signal, a visible laser optical system generating visible laser light to be emitted toward the target and receiving the visible laser light reflected from the target to be converted into a visible electrical signal, and a calculator calculating a first distance value from the visible electrical signal to obtain a number of repetitions of the NAR while measuring a distance to the target and using a second distance value calculated from the number of repetitions and the near-infrared electrical signal to obtain a distance to the target.
