SPIE 3572, 3rd Iberoamerican Optics Meeting and 6th Latin American Meeting on Optics, Lasers, and Their Applications, 294 (July 6, 1999); doi:10.1117/12.358384; http://dx.doi.org/10.1117/12.358384http://hdl.handle.net/10784/4240It was implemented the Lau effect with a grating registered in a BSO crystal. Two different arrangement were analyzed. In both cases, it is possible to control the visibility and to produce the contrast inversion of fringes, by properly setting the pass plane orientation of an analyzer located at the crystal output.eng© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
