Zusammenfassung:	A multi-laser rangefinder is disclosed in the present invention. The multi-laser rangefinder includes a first laser module, a second laser module, a sensor, and a process module. The first laser module is utilized to generate a first laser. The second laser module is utilized to generate a second laser. The sensor is utilized to receive the first laser reflected by a first obstacle and the second laser reflected by a second obstacle. The sensor is utilized to generate a sensing signal after receiving the first laser and the second laser. The process module is utilized to analyze a first central spot of the first laser and a second central spot of the second laser from the sensing signal, and calculate a distance between the first obstacle and the multi-laser rangefinder and a distance between the second obstacle and the multi-laser rangefinder. A method of distinguishing reflection of laser is also disclosed in the present invention.
