After discussing the out-put characteristic of optical triangulation system in detail, some points of the relation between nonlinearity of triangulation and optical system parameters are concluded. These parameters include included angle, the magnification of imaging lens and objective distance of imaging lens. Then, to correct the nonlinearity a new method-asymmetrical gains method has been developed, the principle and the theoretic calculation result are given eventually.
