A modified two prism optical configuration to improve the performance of surface plasmon resonance based sensor systems in bio and chemical analysis is proposed in this paper. This proposed cost effective approach improves the surface plasmon detection sensitivity by keeping the SP interrogation spot stationary during SPR angular rotation. The proposed concept is validated both theoretically as well as experimentally.
