Abstract
A spectroscopic device is disclosed. The spectroscopic device can include a beam collimation structure with a white light source. The beam collimation structure can also include a lens configured to generate a collimated light beam. The spectroscopic device can also include a polarization modulation structure. The polarization modulation structure can convert the collimated light beam into a common path light beam. The common path light beam can include a delayed component and a polarized component. The spectroscopic device can include a dual spectrum sensing structure. The dual spectrum sensing structure can sense a normalized spectral Stokes vector in real time speed.
