• In this paper we propose novel method possessing high fidelity and versatility for surface defect detection based on the spatially filtered dynamic speckles. It is shown that resolution of proposed method depends on the geometrical parameters of the optical system. The feasibility of the novel method for surface defect detection is demonstrated by experimental results which are in good agreement with theoretical estimations
