Light propagation obeys Fermat's principle, and an important inference of principle is the optical Lagrange equation, from which light trace can be determined with a given refractive index. Here, we consider inverse problem how to derive index distribution planar geometric system once predetermined. Based on propose dynamic equation model associates trace. With consideration certain trace, illustrate process solving partial differential through first integral method. By setting function...
Diffusion models are rapidly transforming the field of computational materials design. This review examines their application to 3D molecular and crystal structure generation, focusing on key challenges recent advances. We analyze how equivariance principles manifold learning contribute generating physically realistic structures. discuss innovations in symmetry-preserving generation multi-property directed A critical assessment is provided methods improve sampling efficiency, incorporate...
A simple technique has been found to eliminate the nonlinearity of a heterodyne interferometer by using phase compensation system with rotated polarizer set up before detector. This is generally valid for caused possible optical sources, such as ellipticity, and nonorthogonality incident laser polarization states, imperfections beam splitter retardation plates, well variation polarizing states glass mirror transmission, losses power misalignment interferometer. With this method, elimination...
Subdivision is one of the essential methods to improve measurement resolution optical instruments. A new method proposed solve lambda/16 bidirectional subdivision and direction recognition for orthogonal interference signals by constructing two sets reference using zero-cross detection. The experimental results prove that efficient has good real-time performance field-programmable gate array realization. This easy realize use electronic design automation tools can be widely used in signal...
To minimize the measurement uncertainty of one dimensional length measurements on line scales, linear encoders and interferometers PTB in cooperation with Dr. Johannes Heidenhain GmbH had built up a new comparator. The Nanometer Comparator [1,2] has already proven its performance during incremental scales an expanded below 5 nm [3,4,5]. Due to introduction double multiple exposure advanced lithography techniques overlay registration metrology requirements will drastically increase so that...
Periodic nonlinearity that ranges from tens of nanometers to a few in heterodyne interferometer limits its use high accuracy measurement. A novel method is studied detect the errors based on electrical subdivision and analysis statistical signal Michelson interferometer. Under movement micropositioning platform with uniform velocity, can by using regression Jackknife estimation. Based simulations, estimate influence other noises for dimensions measurement
Effects of site preference, phase stability and brittle versus ductile behaviors W, Mo, La Ce in TiAl have been investigated by using the first-principles calculations. The results show that transition elements W Mo can effectively stabilize B2 except rare earth or Ce. Elastic modulus ductility be improved for ternary addition there is a plastic from intrinsic brittleness to with due transition. competitive mechanisms between opening microcracks dislocation emission increased mainly...
In the measurement system of interference fringe, nonorthogonality error is a main source that influences precision and accuracy system. The detection elimination has been an important target. A novel method only uses cross-zero counting proposed to detect eliminate in real time. This can be simply realized by means digital logic device, because it does not invoke trigonometric functions inverse functions. And widely used bidirectional subdivision systems Moiré fringe other optical instruments.
