61, Augustin Fresnel " , " Nature is not embarrassed by difficulties of analysis. ", "
62, Experiments on dynamic focusing control of the TN-LCSLM based on Fresnel zone lens are carried out. Measured focal lengths are in good agreement with the designed ones.
63, We use the thin film deposition to make 16 step fresnel lens, which can obtains lightweight system, miniaturization and increases free degree of the design.
64, Because the stack considers different geometry of underground reflectors and is stack within the Fresnel zone, the method more approaches to real underground geologic situation.
65, And after employing UV light to cure the resin, the Fresnel lens collector on the PC substrate is fabricated. The Fresnel lens collector on PC substrate is tested in the sunshine.
66, The limitation of far region Fresnel - Kirchhoff formula in transient problem is dis - eussed.
67, In many cases, the Simpler Huygens - Fresnel treatment will prove quite adequate for our purpose.
68, The results consist with the theoretical calculation using the Fresnel - Kirchhoff's formula in considering incident Gaussian beam.
69, The optimum measuring position of virtual source in Fresnel double prism experiment is found by derivation.
70, The lens may take a variety of shapes, including Fresnel features, and may focus, collimate, or defocus the ultrasonic energy.
71, By using Fresnel diffraction, we get the imaging and pseudo-phase-conjugation properties of the optical array with large radius of curvature which is composed by many optical elements.
72, Theory of Fresnel scale diffraction and imaging rule of optical mode were used to investigate the resonator with internal lens and basic structures of equivalent resonator are introduced.
73, The first Fresnel zone radius can be treated as lateral resolving power of seismic data approximately.
74, The optical design and optical efficiency of line focus cylindrical Fresnel lens for solar concentrator are discussed.
75, We simulated the light exposure distribution of the mask and structure of the Fresnel lens in computer.
76, Diffractive efficiency of Fresnel lens is important factor to evaluate the quality of Fresnel lens.
77, The one dimensional Fresnel zone phase correcting principle can be applied to a cylindrical reflector to construct a new type of point source feeding reflector.
78, From the Fresnel diffraction equation, we calculated the intensity distribution of the FHB in free space, and found that there is an interested propagation property of the FHB before the focal plane.
79, The Fresnel diffraction formula and the Fourier transforms are used to get the intensity distribution formula.
