Near-field induced polarization imaging with a solid immersion lens (SIL) is used to provide high lateral resolution compared with conventional far-field microscopy. In addition, a new technique is used to obtain height information from the near-field induced polarization (cross polarized) image. Several optical data storage samples, including DVD-R, DVD-RW, BD-RW, are studied with this imaging technique. A calibration target indicates an accuracy of ±2nm for obtaining height information.
