Therefore, a person skilled in the art will generally determine the size of the spot diameter generated by the mirror field according to experience, and then select a heat absorption groove longer than the spot diameter. In addition, the width of the heat absorption groove on the U-shaped section can be as small as possible, and is generally smaller than the radius of the light spot, so as to ensure the accuracy of the measurement result. Because the narrow and long-strip-shaped heat absorption groove is formed, the absorption of the energy of the light spot is more sensitive, and whether the opening reaches the diameter position of the light spot can be more accurately reflected.
