Image of FIG. 1.
FIG. 1.

Visualization principle of inverted domain structures used in the SHGIM.

Image of FIG. 2.
FIG. 2.

Numerical calculations of and focus position dependences of SH intensity in the noninterference case. The Rayleigh length is assumed to be constant.

Image of FIG. 3.
FIG. 3.

Schematic illustration of the optical system of the SHGIM. Here HWP indicates a half-wave-plate and TFP a thin film polarizer. The attenuator (At) consists of HWP and TFP.

FIG. 5.

Results of focus scan of SH intensities using the component along the axis of MgCLN: (a) noninterference case, (b) interference case with , and (c) interference case with .

Dimensions and orientations of (a) MgCLN and (b) PPSLN samples. , , and indicate the crystal principal axes.

Image of FIG. 7.
FIG. 7.

Results of focus scan of SH intensities along the axis of PPSLN: [(a) and (b)] noninterference and interference cases for , respectively, and [(c) and (d)] noninterference and interference cases for , respectively.

Image of FIG. 8.
FIG. 8.

SHG interference image in an cross section: (a) experimental result and (b) result of the numerical simulation corresponding to (a).

Image of FIG. 9.
FIG. 9.

(a) SHG interference tomography images at cross sections and (b) 3D image of PPD structure constructed with the images of (a). A small difference in the reference frame between images is caused by a tiny inclination of the sample which is estimated to be 2º of the arc.

Image of FIG. 10.
FIG. 10.

The dependence of the integrand in Eq. (A1) on : (a) simulation result with negative for the component of MgCLN and (b) result with positive for the component of MgCLN.
