Design and Simulation of a Large-Angle Electro-Optic Laser Scanner with Cascaded Ferroelectric Domains
Aiming at the optical scanning of wide field-view with high speed a large angle electro-optic scanner was designed based on the deflecting property of the prism domains.It mainly consists of one parabola deflector and ten half-parabola deflectors with cascaded ferroelectric prism domains.By design optimization the structure parameters of scanner were given and the overall size of scanner is 130.0 mm×16.0 mm×0.5 mm.When the applying electric field is ±10.09 V/μm the deflecting range is ±30.6°.Using the beam propagation method (BPM) the capability of scanning was evaluated and the simulation results show that the deflector has good deflecting properties.The simulation analysis is consistent with the theoretical calculation.
