Abstract: An image inspecting device is adapted to inspect the difference value between the locations of first and second images. The image inspecting device includes an image catching unit and a light processing unit. The light processing unit is adapted to project the first and second images on the image catching unit.

Abstract: A head mounted display includes two imaging apparatuses and at least one optical compensator. The imaging apparatuses can form two virtual images respectively in front of two eyes of a user. The optical compensator can modulate wavefront of the image beams of the virtual images so as to adjust the positions of the virtual images. In this manner, the positions of the two virtual images can be adjusted to substantially coincide with each other. The present invention also provides an image adjustment method for a head-mounted display.

Abstract: The present invention relates to a method to control the nucleation and transverse motion of 180° inverted domains in ferroelectric nonlinear crystals. It includes a process composing of a high temperature oxidation of the first metal layer and a pulsed field poling of the second electrodes. The main object of present invention is to provide domain inversion of ferroelectric nonlinear crystals with field control the nucleation and transverse motion of inverted domains and two-dimension nonlinear photonic crystals for time-domain multiple-wave simultaneous lasers and space filter function. Another object of present invention is to provide space-charge effect for screened edge field beneath the metal electrode, The other object of present invention is to provide the constraint of inverted domain nucleation in the oxidized electrode for arbitrarily geometrical form of 2D ferroelectric lattice structure.
