Results and Conclusion\ The number of beams is increasing in geometric series when the light propagates in the two layer system, and it is necessary for study of the interference pattern of the system and for further development of Fabry Perot interferometer.
A digital angle measurement technique based on Michelson interferometer is introduced in the paper. Through changing the angular displacement into linear displacement,using special circuits to subdivide and measure the interference pattern,exact measurement for a big angle is realized.
In the shallow water waveguide, the interference pattern and dispersion characteristic, which are the most important coherent properties of sound field, can be characterized by the waveguide invariant β and used for acquiring the information on source localization.
The paper describes the principle that using Optical Computer Tomography (OCT) method to reconstruct inside 3-D image of a subject and discusses the image processing method of homography interference pattern by using OCT.
We show that when the bandwidth of the noise spectrum is increased, the first-order interference pattern disappears while the sub-wavelength pattern fringe emerges in the intensity correlation measurement.
Thin films of the hyperbranched azo polymers were used to fabricate surface-relief-gratings (SRGs) by exposing them to an interference pattern of Ar+ laser beam at modest intensities (150 mW/cm2).
Surface-relief-gratings (SRGs) were fabricated on the polymer film after being irradiated by interference pattern of Ar+ laser beams for 1,000 s.
In a composite containing 0.26 wt % SWNT, the diffraction grating is displaced by 5° relative to the interference pattern, the result that is presumably due to the close mobility of unlike charge carriers.
It has been shown that the main factors determining the interference pattern in the plate are the plate thickness, absolute value of the modulus (density) variation, and spatial derivative of the modulus.
