Angular magnification method of liquid crystal optical phased array based on telescope system

A novel angular magnification method based on a telescope system is proposed in this paper to achieve liquid crystal optical phased array (LCOPA) wide-angle deflection. The optics transfer matrix of telescope is studied and the angle magnification effect is derived. The transformation formulas of a Gaussian beam through the telescope system are also derived by using the ABCD law. Simulation and experiment have been done to magnify the angle that deflected by a LCOPA. This method is feasible and convenient to obtain wide-angle steering for a LCOPA.
