Arbitrary n-step phase-shifting Fourier single-pixel imaging
Figures & Tables(9)
Fig. 1. Simulation results of “Cameraman” reconstructed by FSI for 3–6 steps. The 3-step image of Case 3 is left blank because it is only valid for n > 3.
Fig. 3. Images for the binary object reconstructed by FSI for 3–6 steps. The 3-step image of Case 3 is left blank because it is only valid for n > 3.
Fig. 4. Images for the gray-scale object reconstructed by FSI for 3–6 steps. The 3-step image of Case 3 is left blank due to its validity for n > 3.
Fig. 5. Comparison of images of the “astronaut” object reconstructed by FSI for 3–6 steps under different light intensities. (a) Strong light. (b) Weak light.
