| Abstract: | In this paper, we give the classifications of the singularities of the Spherical Darboux imaged of a nonlightlike curve in Minkowski 3 - space. Moreover we establish the relationships between singularities of these subjects and geometric invariants of curves which are deeply related to the order of contact with helices. |
