Abstract
This paper demonstrates that a panoramic annular lens (PAL) can be used to record moiré fringes corresponding to the displacement of a grating of constant pitch fixed to a cavity wall. Definitions and parameters used to describe the imaging characteristics of the PAL are combined with the mapping function of the lens to develop analytical relationships sufficient to predict moiré fringe loci. Experimental results verify these analytical arguments. The paper also includes discussions of the panoramic annular lens, radial metrology, and potential applications of the panoramic moiré method.
