【Abstract】 Liquid crystal phased array can not only establish the space laser communication link between multiple points in the space laser communication technology, but also replace the precision mode of piezoelectric bias mirror. The application trend of liquid crystal phased array is described in this paper. Based on the principle of electro birefringence of liquid crystal molecules and the deflection of multi-slit diffraction beam in liquid crystal phased array, a scheme of aiming, capturing and tracking for piezoelectric biased mirror with terminal is proposed. Taking "one to two" space laser communication terminal as an example, the scheme and link operation mode of multi-point space laser communication terminal based on liquid crystal phased array are proposed, and the advantages of the scheme are analyzed.更多还原
