Abstract
We present a method to obtain instantaneous quadrature components of the complex interferometric signal for depth-ambiguity free and full range optical frequency domain imaging, based on the Pancharatnam-Berry phase. This wavelength independent method allowed for a complex conjugate suppression of 45 dB, over an optical bandwidth of 80 nm. Furthermore, we investigated the versatility of this setup to perform polarization sensitive measurements. The sample Jones vector was fitted using the Newton-Raphson method, allowing sample birefringence and optical axis calculation.
