This paper proposes a novel Micro-Opto-Electro-Mechanical-System (MOEMS) based beam steering method mainly
designed for far operating distance applications. The proposed system incorporates a MOEMS analog mirror developed
by Texas Instruments Inc. as core component and a beam expanding telescope. The analog mirror can change angle
within a ±5° range of mechanical rotation in two axes. The expanding telescope could reduce beam dispersion caused by
diffraction of the mirror's boundary. Expressions of steering equation, steering range and angular resolution are deduced.
Steering trace and far field steering beam patterns are simulated. Analyses on main performance of the system are
