Paper Abstract

Two-beam interferometry enables information coding in the shape/orientation and contrast/intensity modulation of the fringes. There exists an abundant literature on decoding the interferogram phase whereas there are only a few studies dealing with the second type carrier decoding. This paper is focused on the two-beam interferogram intensity modulation analysis using temporal phase shifting. The influences of most important experimental errors are studied using computer simulations and laboratory works. Null and finite-fringe detection modes are compared. Phase-shift histograms and their lattice-site representations are investigated to aid the experimental error identification.
