    Abstract: An optical sensing device is provided, including a first polarizer, a second polarizer, wherein the first polarizer and the second polarizer have respective transmission axes aligned in orthogonal directions, an SPR sensor arrangement including an SPR sensing surface, the SPR sensor arrangement arranged to receive an incident light beam passed through a polarizer to be reflected at the SPR sensing surface and transmitted through a second polarizer to provide a transmitted light beam, a detector arrangement configured to detect the transmitted light beam, the transmitted light beam including a sensing signal and a reference signal, and a processor electrically coupled to the detector arrangement, the processor configured to perform a subtraction operation between the sensing signal and the reference signal. The optical sensing is based on a differential measurement scheme. The subtraction between the sensing signal and the reference signal cancels the common path noise and enhances the sensor resolution.

    Abstract: Polarization-sensitive optical image measurement is subject to a non-negligible bias, and consequent deviation in birefringence, in a surrounding range of low SN ratios (signal-to-noise ratios) and low signal strengths; however, this deviation in birefringence is removed to make accurate quantitative measurement possible. Noise-containing OCT signals obtained by polarization OCT are processed using a birefringence calculation algorithm, to obtain measured birefringence, after which noise is statistically adjusted to simulate a measured birefringence distribution and determine the noise characteristics of the measured birefringence values, and then Monte Carlo calculations are repeated by assuming different values for the noise level and the true birefringence value, respectively, to form three-dimensional histogram of combinations of true birefringence values, SN ratios, and measured birefringence values, after which specified measured birefringence values and SN ratios are assumed from the three-dimensional histogram information to obtain a true birefringence probability density distribution, and true birefringence values are estimated from the true birefringence probability density distribution.
