Inventions of the new instruments for pointing and measuring of any heights of trunks and for remote-measuring the upper diameters by using the red-laser-pointer

The method of pointing and measuring any heights of trunks is based on the theory of the similar triangle. The new apparatus, that is able to point and measure any heights of trunk, is constituted of the red-laser-pointer that is able to move vertically on the observing point, the horizontal-scale that is able to lengthen or shorten its length as 1/100 distance from the observing point to measuring trees, and the vertical-object-scale that has thin horizontal-frames every centimeter as a ladder. When the length of horizontal-scale is adjusted to 1/100 distance from the observing point to the measuring tree, and when the laser-beam is radiated through observing point to the measuring tree, through nearly upper (or under) edge of the thin horizontal-frames of the vertical-object-scale, the any numbers of the thin horizontal-frames of the vertical-object-scale that are radiated by the red-laser-pointer are equal to the meter-lengths of the trunk of the measuring tree. And then the upper diameters that are pointed by the red-laser-pointer can be measured from the remote points as the same distance between two other parallel beams of the two red-laser-pointers that are attached on the remote calipers instead of its arms
