From: Spatial correlations and optical properties in three-dimensional deterministic aperiodic structures
Measured transmission patterns for different modulation strengths.
(a) Pattern obtained when no sample is present. The Cassegrain objectives are positioned such that the excitation (collection) focus is placed at the bottom (top) of the structures when introduced into the light path. (b) Periodic structure with equal elements. (c,d) Weakly modulated (±10%) (c) and full 1/τ (±23.65%) modulated (d) Rudin-Shapiro structure. Structure height is 60 μm. Patterns are shown at a wavelength of λ = 1.7 μm.
