Optical quantum weak measurement coupled with UV spectrophotometry for sensitively and non-separatedly detecting
Abstract:
Based on the theories of quantum weak measurement, we built a set of linear common-path optical weak measurement systems in frequency domain for detecting chiral molecules. The polarization resolution with this system to detect the optical rotation of chirality molecules is nearly two orders of magnitude higher than that of conventional polarizers. Combined with ultraviolet spectroscopy, the purity of the proline enantiomers mixture was detected. The purity resolution can reach to 0.14%, which is comparable to the liquid chromatography. Weak measurement combined with ultraviolet spectroscopy to non-separatedly detect the purity of chiral enantiomers has great application potential in the pharmaceutical industry.
