Claim 1:
2. The dual-filter-based transfer alignment method under dynamic deformation according to claim 1, wherein in step (1), the geometrical analysis on the flexural deformation is carried out and the expression of coupling angle Δ{right arrow over (ϕ)} resulted from the dynamic deformation of the carrier and movement of the carrier is derived as follows:

Δ{right arrow over (ϕ)}=M{right arrow over (ω)}θ,

wherein, {right arrow over (ω)}θ={right arrow over ({dot over (θ)})}, and M is expressed as:, M
