Fresnel-zone-like moiré patterns: optical generation and plasmonic modulation with proposed surface profilometry application

Abstract

A novel scheme of surface plasmon resonance-assisted Fresnel-zone-like moiré pattern generation has been theoretically and experimentally investigated in a dual shearing environment. Lateral shear is followed by radial shear with the help of a Wollaston prism and a birefringent lens, respectively. The superposition of two contrast-reversed Fresnel-zone-like patterns (FZP) with parallel equi-spaced straight lines interestingly generates the displaced replication of the original FZP, particularly when the lateral shear is of a sufficient amount. Modulation due to plasmonic excitation has also been observed on such patterns for two different substrate materials. Binary representation of radially sheared images has been illustrated and further utilized for the proposed non-contact surface profilometry of metal coatings.
