The CLEAN algorithm performs a deconvolution on the “dirty” input to increase this quantity and obtain the PSF. Cy3 and Cy5 are commonly used molecules that are stochastically activated in a technique that improve this quantity. (15[2])That technique, STORM, can improve this quantity (15[1])in the lateral direction, unlike the similar PALM technique. This quantity is equal to (*) lambda divided by two times the numerical aperture, (10[1])according to a formula (10[1])by (10[1])Ernst Abbe. The angular form of this quantity is given as 1.22 times lambda divided by lens aperture (-5[1])by the Rayleigh criterion. Superlenses made of metamaterials are used to increase this quantity beyond the diffraction limit. For 10 points, name this quantity which is the minimal distance (-5[1])between two points that can be distinguished. ■END■ (10[1]0[2])
