To implement a phase detection system, based on surface plasmon resonance (SPR).
Optical phase detection includes both a step for generating first light waves having first polarized light and second light waves, having polarized light offset from the first polarized light and a step for providing relative delays between the first light waves and the second light waves. The relative delay generates an frequency offset between light waves, when a wavelength is adjusted over a specified wavelength range. A step of guiding the first light waves and the second light waves to a target provides third light waves and fourth light waves are provided. A polarized light component of the third light waves and a polarized light component of the fourth light waves are detected, and signals detected in the frequency offset are provided. The optical phase detection includes a step for extracting the phase difference, caused by the target between the polarized light component of the third light waves and the polarized light component of the fourth light waves.
