Abstract
The invention concerns a micropolarimeter comprising an analyzer (,) and a detector (,) located past the analyzer in the direction of radiation and presenting a number of segments N,which is higher than or equal to 3 (,). The invention seeks to provide a micropolarimeter with no moving parts, with a high polarization index, for use for polychromatic light, so small that it can detect the ray of common lasers in one single measurement step without it being necessary to enlarge it, and capable of being converted in a simple manner into a complete Stokesmeter. To that end, the analyzer (,) consists of a radially symmetrical flat disk (,) produced in a polarizing material with which the polarization rests on absorption effects inside said material, the surface of the analyzer (,) being greater than or equal to the surface of the detector segments (,)
