摘要：

We have measured the spatial distribution of birefringence DELTAn for two ferrofluids (Fe2C0O4 and gammaFe2O3), subjected to a continuous magnetic field perpendicular to the propagation direction of a laser beam. These measurements have been made for small thickness of ferrofluids, using an argon laser (514 nm) and a CCD camera. The samples show a linear dependence on ferrofluid concentration and thickness; the results show the possibility of using ferrofluid thin plates in active imagery.
