Optical sensing devices with SPR sensors based on differential phase interrogation and measuring method using the same |
摘要 |
Disclosed is an optical sensing device, which comprises a light source emitting a light; a beam splitter; an SPR sensor unit comprising a sensing surface; and a detecting mechanism; and a converting unit converting the first beam and the second beam from the optical device into a two-dimensional interference fringe pattern. From the above-mentioned configuration, an extra phase shift of a detection beam in SPR phase measurement is obtained. The differential measurement approach has shown to achieve a sensitivity figure significantly better than the best result that can be obtained from the prior art in the field of the measurement based on an SPR sensor.
