“Modeling and Analysis of Experimental Atomic Force Microscope Images of Hard Colloidal Particles"
The fundamentals of atomic force microscopy of hard colloidal particles are described: image modeling, image deconvolution, calibration of tip-shape with hard spherical colloidal particles (not necessarily monodisperse!). Necessary easy-to-use algorithms (many details) and examples of experimental data analysis are also presented.
The Fortran sources of the modeling / deconvolution / calibration program mentioned in the above paper are available upon e-mail request (see below).

Simplified idea of topographical AFM:
Comparison of AFM image (raw) with deconvoluted image for AFM cantilever with large sperical tip apex (e.g. worn-out tip or a tip with a colloidal particle glued to its end) - image features' half-height width are marked:
(1) Creation of AFM image, (2) deconvolution of AFM image (for the known tip shape), (3) deconvoluted tip shape (e.g. calibrated on sperical particles).
