Reconstruction results using depth-wavelength relationship. (a) IPSF(λ = 617 nm, u = v = 10 cm), (b) IPSF(λ = 530 nm, u = v ≈ 12 cm). (c) IO(λ = 617 nm, u = v = 10 cm), (d) IO(λ = 530 nm, u = v ≈ 12 cm). (e) Cross-correlation between (a) and (b). (f) Cross-correlation between IPSF(λ = 617 nm, u = v ≈ 9 cm) and IPSF(λ = 530 nm, u = v = 10 cm). Reconstruction results by cross-correlating (g) (c) with (a), and (h) (c) with (b), (i) (d) with (b), and (j) (d) with (a). The square, circle and triangle represent similar intensity signatures. (k) The object and image distances are varied from 6 to 12 cm and the wavelength was varied from 550 to 650 nm and the corresponding spatio-spectral signatures are cross-correlated with IPSF(λ = 617 nm, u = v = 10 cm). (l) The object distance is varied from 6 to 12 cm and the wavelength was varied from 550 to 650 nm and the corresponding spatio-spectral signature is cross-correlated with IPSF(λ = 617 nm, u = v = 10 cm) resulting in a single maxima.
