Research output: Patent


A wavefront sensing technique using Polarization Rotation INTerferometry (PRINT) provides a self-referencing, high-resolution, direct measurement of the spatially dependent phase profile of a given optical beam. A self-referencing technique is used to create a reference beam in the orthogonal polarization and a polarization measurement to measure the spatial-dependent polarization parameters to directly determine the absolute phase profile of the beam under test. A high-resolution direct measurement of the spatially-resolved phase profile of one or more optical beams is realized.
