Deformation measurement of circular steel plates using projected fringes

Abstract

Abstract Fringe projection is a versatile method for mapping
the surface topography. In this paper, it is used to measure the
deformation of steel plates under static penetration. Here, the
surface shape changes continuously. Therefore, it is important
to minimize the registration time. To achieve this, we apply a
method of fringe location with subpixel accuracy that requires
only a single exposure for each registration. This is in contrast
to phase shifting techniques that require at least three separate
exposures.
