Abstract

Weak measurement technology can be used to achieve ultra-precision modulation of variables. Based on this, to achieve precise modulation of beam deflection, we establish a model of beam propagation using weak measurement, theoretically deduce the general formula of the deflection angle, and illustrate the general process of precise modulation of the angular shift of the beam. By controlling the post-selection state of the weak measurement, the angular shift of the beam can be precisely regulated. The deflection angle is proportional to the imaginary part of the weak value. We describe a simulation and discuss how precise angle tuning can be achieved by controlling experimental parameters.
