Theory of Spatial Moiré Fringes

Not Accessible

Your library or personal account may give you access

Abstract

The obstruction theory and analytical geometry were used to determine the equations of the rays emerging from a pair of gratings separated by an air gap, and a theory of the formation and location of spatial moiré fringes was developed. Fringes resulting from plane gratings lie in planes; the location and inclination of these moiré planes depend upon the magnitude and sign of the following parameters: (i) the linear disparity, (ii) the air gap, and (iii) the relative grating inclination.

The appearance of spatial moiré fringes from any point of view and the resulting interfringe spacing on a camera image plane were investigated. In particular, the appearance of the spatial moiré fringes, which have been utilized in strain analysis, was investigated. Experimental evidence satisfactorily supported the theoretical findings.
