Abstract
An optical sensing device including a source unit configured to generate a polychromatic light beam containing p-polarized beam and s-polarized beam; an interferometric unit configured to introduce birefringent retardation for generating optical path difference between the p-polarized beam and the s-polarized beam; a SPR sensing unit configured to receive both p-polarized beam and s-polarized beam and induce a SPR effect to the p-polarized beam associated with a target sample; and a detection unit for detecting target sample characteristics by obtaining an interference spectrum of the p-polarized beam and the s-polarized beam from the SPR sensing unit.
