The STED CW system is based on Leica's STED technology, which scales down the scanning spot to sub-diffraction size by switching off fluorescence in the periphery of the excited area.
Like the scanning spot triangulation systems, the line setup delivers a height profile along the projected structured light line (Iakovou, 2009).
where diamtr[1] is the number of pixels which form the curve segment between [c.sub.1] and one of the intersections at which the curve and the edges cross each other (i.e., diamtr[1] is half of the length of the curve segment); u[1 j] and l[1 j] are pixel values of they th scanning spots when a scanning is conducted from [c.sub.1] to each of the upper intersection and the lower one along the curve.
where [lenght.sub.m] is the number of the shifts in [R.sub.m], diam r[k] is the number of pixels which form the curve segment between [c.sub.k] and one of the intersections at which the kth scanning curve and the edges cross each other, and then, w[k, j], and l[k, j] are pixel values of the jth scanning spots when the kth scanning is conducted from [c.sub.k] to each of the upper intersection and the lower one along the k th scanning curve, respectively.
