- Cesar Augusto Sciammarella (born August 22, 1924) is an Argentine civil engineer who made significant contributions to the field of experimental mechanics. In the last decade, he has extended his pioneering developments in moiré, holography, and speckle interferometry methodologies down to the nanometer level. These efforts have enabled optics to be applied beyond the classical Rayleigh limit, reaching the nanometre range, and allowed electron microscopy to reach resolutions of the order of atomic distances. His research is widely used for 3D reconstruction and stress and strain analysis. In his Doctoral Thesis on the Moiré method, he extended the Continuum Mechanics model originally developed by Dantu to large deformations. He developed fundamental equations on the properties of moiré fringes, signs conventions. He applied the moiré method to the solution of a plasticity problem. This was the first complete analysis of a non elastic problem with the moiré method. Dr Sciammarella generalised the concept of fringe order in methods that measure displacements using Fourier analysis in the process of formation of the fringe images. He proved formally that the orders could be represented by real numbers instead of integers, as was usual at the time of his publication. In 1966, he presented a full model of the moiré fringes as phase modulated signals and provided a method to get displacements and strains for moiré and photo-elastic fringes. He introduced in the literature the Fourier method as a tool for fringe pattern analysis. His model stands today as a standard model used in the fringe analysis method. (en)
