Paper Abstract

There are two light sources in Femtosecond laser tracker, the center wavelengths of which are different. In order to achieve precise distance, light beams from the two sources should be combined. In this paper, key technology of light path alignment for femtosecond laser tracker based on double optical wedge is presented. Precise steering of incident light beam can be realized by changing the angle of the double optical wedge. Method for adjusting the angle and translation of light beam using two pairs of double optical wedge is proposed. Also mathematical model on the basis of vector superposition method is established to correct offset of light beam, which is validated with Zemax.
