lspsi: Phase Shifting Interferometry

In mlpeck/zernike: Zernike Polynomials

Phase Shifting Interferometry

Description

Least squares fitting of phase shifted interferograms.

Usage

lspsi(images, phases, wt = rep(1, length(phases)))
lspsiC(images, phases, wt)

Arguments

images	An array containing the interferogram images
phases	A vector of phase shifts
wt	A vector of weights

Details

images is a 3 dimensional array with dimensions nrow x ncol x length(phases), where nrow and ncol are the number of rows and columns in the individual interferogram images.

lspsi reshapes the image array into a matrix and calls lspsiC which in turn calls the compiled C++ routine.

Value

A list containing the following components:

phi	Estimated wrapped wavefront phase.
mod	Estimated modulation
