Abstract

Theoretical and experimental investigation of surface plasmon resonance (SPR) assisted radially sheared interference imaging using a birefringent lens having two longitudinally shifted focal points has been reported. As Wolllaston prism can introduce lateral shear between the two mutual orthogonal polarizations of radially sheared pattern, Moiré-like pattern is produced at overlapping region of those patterns. Brief theory and experimental demonstration of coherent and incoherent Moiré fringe generation has been done. Surface plasmon resonance (SPR) mediated Moiré pattern has been demonstrated which can be further utilized for other nanophotonic applications.
