If the laser tracker is used for measuring the surface waviness, the light emitting part of the measuring device emits laser, meanwhile, the spherical reflector slides along the measured surface, the distance information from the light emitting part to the reflector is combined with the laser emission angle information to calculate the center coordinate of the spherical reflector, and then the center coordinate is converted and calculated into the surface waviness measurement data.
