Paper Abstract

We suggest a linear polarization sensor, which has been developed for the Shack-Hartmann wave-front sensor. Our system is classified into three parts. First, polarization filter using wire-grid-plate structure selects only one polarized wave between two linear orthogonal polarization states. Second, graded index layer refracts the wave passed and gives the wave-front distortion. Third, a lens array, one part of the Shack-Hartmann wave-front sensor, focuses the wave on focal plane. We can detect linear polarization state through measuring displacement of the spot centroid. This study on polarization sensor can offer help on vector field sensing, which is crucial to obtain a complete description of light in nanoscale device.
