Abstract
A laser distance measurement device, which mainly comprises: a laser beam emitter which can emit visible laser beam; a first reflector; a second reflector; in which when the laser beam emitter emits laser beam on the first reflector, 50% of the laser light goes through the first reflector and the other 50% of laser light reflects upward at 90 degrees, and when the 50% of laser light passed from the first reflector impinges on the second reflector, the second reflector reflects 100% of the laser light to form an intersection point with the 50% laser light previously reflected in which the intersection point is used as the calibration distance measurement point and a point is located on the horizontal edge of a precision scale; when moving a second reflector on the scale, the vertical edge and the horizontal edge forms a certain ratio; when the intersection point of the first reflector and the second reflector moves to another distance measurement point, the minute scale on the precision scale reads out the precise distance of the distance measurement point on the vertical edge.
