Claim:
1. A distance measuring laser pointer comprising: at least one laser source emitting a light ray; and two optical elements disposed in front of the at least one laser source, receiving and transferring the light ray into a first conic light beam and a set of multiple second conic light beams; wherein the first conic light beam projects a first light pattern on a surface of a target, wherein the set of the second conic light beams project a second light pattern on the surface of the target, wherein an intersection between the first light pattern and the second light pattern changes position depending on variation of a distance between the distance measuring laser pointer and the target to indicate the distance; wherein the at least one laser source includes a first laser source and a second laser source capable of emitting two light rays, and the two light rays respectively pass through and are transferred by the two optical elements into the first conic light beam and the set of the multiple second conic light beams.
