  • MEASUREMENT APPARATUS OF WAVEFRONT AND POLARIZATION PROFILE OF VECTORIAL OPTICAL FIELDS
    Publication number: 20200011737
    Abstract: An apparatus measures the transverse profile of vectorial optical field beams, including both the phase and the polarization spatial profile. The apparatus contains a polarization separation module, a weak perturbation module, and a detection module. Characterizing the transverse profile of vector fields provides an optical metrology tool for both fundamental studies of vectorial optical fields and a wide spectrum of applications, including microscopy, surveillance, imaging, communication, material processing, and laser trapping.
