Distance measuring laser pointer
Abstract:
A distance measuring laser pointer has at least one laser source 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. The first conic light beam projects a first light pattern on a surface of a target, and the set of multiple 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.
