Abstract

This paper proposes a procedure for automatized fine-focusing of particles’ image in digital microscopy. First, analytical formulas for a calculation of axial defocus are derived using the complex amplitude propagation. Afterwards, the formulas are used for a design of an iterative algorithm for the fine-focusing. Uncertainty analysis and error simulations are then presented. In the final part of the paper, the method is verified by a simple experimental setup. The proposed strategy can find utilisation in many practical applications of automatized processes, not only in digital microscopy.
