An expression for logarithmic light intensity fluctuation variance of partially coherent light passing through atmospheric turbulence is derived by using Andrews scintillation model on the basis of Rytov variance.
Fresnel diffraction of the grating illuminated with the polychromatic light source is theoretically analyzed with the theory of partially coherent light, and the general formula of the diffraction intensity of the grating is obtained. This formula is applicable to any kind of illuminance pulsed or CW. The theoretic results show that the average diffractive intensity distributions of the grating illuminated by the different source with the same spectrum are the same.
The seismic responses of the roof structure of the Tianjin Olympic Center Stadium subject to the uniform excitation, the traveling-wave excitation, and the multi-support excitation considering the partial coherence effect and the seismic nonstationarity, under one-dimensional and three-dimensional random earthquake motions were numerically simulated.
Based on the partial-coherent theory, the apparent transfer function and energy distribution are respectively used as evaluation indices to calculate the optimal imags plane position of partial-coherent optical system and the relationship with coherency. spatial frequency and aberration is discussed.
It is shown that the partial coherence of the interacting waves induces novel effects on the dynamics of crossing sea states.
In cataractous patients, the authors measured the axial length (AL) using both partial coherence laser interferometry (PCLI) and ultrasound biometry (UB), the latter performed by both an experienced and inexperienced operator.
In the course of the derivation of the fourth-order equation we mention the effects of partial coherence on the second-order absorption and stimulated-emission processes.
The results enable a unified treatment of theories of partial coherence and partial polarization to be obtained, and suggest a formulation of a wide branch of Optics in terms of observable quantities only.
A multivariate analysis based on partial coherence analysis was used to correct for head movement.
Measuring displacement fields of curved surface by moire interferometry of partial coherent light
This paper presents a method to measure the in-plane displacement fields of curved surface by moire interferometry of partial coherent light.
The existence of two different critical temperature values confirms the coexistence of partial coherent and coherent electron pairing phenomena in the region below Tcc of the superconducting phase diagram.
