The utility model discloses an optical target paper component used for measuring by a total station, wherein a half rectangular surface of a piece of square optical target paper (1) abuts against one end of a board-rule-shaped steel plate (3) with the width larger than that of the optical target paper and is sealed and fixed by adhesive tape (2), wherein the half rectangular surface is level with one end of the board-rule-shaped steel plate; and the sealed and fixed adhesive tape (2) is exposed out of the one-fourth paper surface outside the optical target paper (1). The other end of the steel plate (3) is provided with a hole, and a bridle or a tether (6) is arranged in the hole in a tied manner. The use manner of the optical target paper has the following advantages: 1. the abrasion of the optical target paper is reduced, the use times of the optical target paper is increased, and use cost is lowered; and 2. measuring precision is improved; and in the measuring course, the total station sends out a laser beam which is emitted on the optical target paper and then reflected to the total station to conduct measuring. The method shortens the effective reflecting range of the optical target paper, and improves the measuring precision.
