Feasibility study of multi-point two-dimensional profile measurement by 3-2-1 and 3×3 sensor layout

New multi-point methods, the six-point method of 3-2-1 sensor layout and the nine-point method of 3 × 3 sensor layout, have been proposed as the two-dimensional profilometry for a machined flat surface. Monte Carlo simulations were carried out and properties of proposed methods were examined. As a r...
