Abstract (en)

[origin: WO02054142A1] The invention concerns a device essentially comprising an electrooptic material plate (6), such as lead lanthanum zirconate titanate (PLZT) for example, whereon are printed electrodes (7 to 10). The electric field generated by applications of voltages (V1 to V4) on said electrodes produces a rotating-axis phase plate.
