Embodiment Construction
[0017] The real-time detection device for ferroelectric crystal domain inversion of the present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention should not be limited by this.
[0018] See figure 1 , figure 1 It is a schematic diagram of the structure of the device for real-time detection of ferroelectric crystal domain inversion of the present invention. It can be seen from the figure that the device of the present invention for real-time detection of ferroelectric crystal domain inversion includes: helium-neon laser 1, filter 2, collimator 3. The first total mirror 4, the second total mirror 5, the dichroic prism 7, the imaging lens 8, the CCD coupler 9 and the computer 10. The positional relationship of the above components is as follows:
[0019] The 633nm beam output by the helium-neon laser 1 is filtered by the filter 2 and collimated by the collimator 3, and then divided into a reflected...
