Distance Measuring Laser Pointer and method thereof

摘要

A distance measuring laser pointer has: at least one laser source being capable of 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, the set of the second conic light beams project a second light pattern on the surface of the target, 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. The distance measuring laser pointer simultaneously indicates a diameter or length of the target when indicating the distance.
