We report the design and first implementation of an active polarimetric imaging system based on the recently introduced concept of polarimetric sensing by orthogonality breaking, which involves a specific crossed-polarization dual-frequency illumination. We describe the laser source architecture and microscope set-up devoted to visible imaging at 488 nm, as well as the specific homodyne detection chain required for orthogonality breaking measurements. The first polarimetric images obtained with this non-conventional approach are presented. The polarimetric contrasts observed validate the polarimetric sensitivity of the technique.
