Fig. 1. Schematic of ADS interference. α is the width of an angular single slit, and ϕ is the angle between dynamic two single slits. q1, q2, and q3 are three points on the mask and oq3 is the angular bisector of ∠q1oq2. P is a point on the far field (with q1P=q2P), which is chosen to observe interferential intensity. θ represents an additional phase on one single slit.

Fig. 2. Sketch of the experimental setup. The inset shows the mask pattern loaded on the SLM.

Fig. 3. I−ϕ curves in polar coordinates when the additional phase θ is zero. The black dots are the experimental data and the green solid curves are fits of the data. M is the theoretical FTC and |Mf| is the modulus of the FTC, which is obtained by fitting the experimental data to the fitting function.

Fig. 4. Contrasted I−ϕ curves between θ=0 (the blue curve) and θ=π/2 (the purple curve) with M=4.3.
