This paper presents a new set of estimation formulae for non-contact 2D displacement measurement by using the principle of triangulation and the position sensitive detector (PSD) as a 2-D range sensor. It has been shown in theory that the new set of formulae outperforms the conventional formulae by providing much more accurate estimate of the 2D displacement. The theoretical analysis has been verified by simulation studies.
