The Optical Aspect of Errors in Measurements of Surface Asperities Using the Optical Profilometry Method
The paper presents the impact of lighting type and direction on measurements of surface asperities using focus-variation microscopy. Particular attention was paid to the direction of lighting when using a light ring. It was pointed out that the lighting direction directly affects the values of the p...
