Figure 4
Deviation in the fringe oscillation due to spectral broadening. Radial intensity is calculated for the 100 nm Au nanosphere, and the results are compared for different spectral bandwidths of = 10−2 in (a) and = 10−3 in (b) relative to = 0 (black solid line with square). The shift in the fringe oscillation period due to the spectral broadening becomes discernible after the mth pixel with m ≃ . |
