Abstract: (731 Views)
In this paper, a surface plasmon resonance (SPR) interferometer sensor is designed based on phase modulation. Phase interfereometery between s and p polarizations, as a probe and reference, is the basise of this optical set up. This sensor is able to detect interference phase shifts due to refractive index changes. This system is considered as a high sensitivity refractive index sensor, which is cheap and does not require a mechanical rotation stage or spectrometer.
