Abstract
Summary from only given. We report a noninterferometric wide field optical profilometry with nanometer depth resolution. The working principle is similar to that of differential confocal microscopy (DCM), except that the axial response curve is generated by wide-field optical sectioning microscopy. Wide-field sectioning microscopy has an optically sectioning ability similar to that of confocal microscopy.
