摘要：Disclosed are optical sensing devices and methods for detecting samples usingthe same. The optical sensing device comprises a source unit configured to generate apolychromatic light beam containing p-polarized and s-polarized components; aninterferometric unit configured to split the light beam into a probe beam passing a firstpath and a reference beam passing a second path and to recombine the probe beamoutput from the first path and the reference beam output from the second path; asensing unit disposed in the first path to introduce a first SPR effect associated with atarget sample to the probe beam; and a detection unit configured to detect targetsample characteristics by obtaining an intensity spectrum of the recombined light beam.The introduction of a polychromatic light source in the optical sensing device increasesthe detection dynamic range and the detection sensitivity.
