Analysis of micro-Fresnel lenses with local grating theory and its comparison with fully electromagnetic methods.

چکیده
We report on a numerical analysis method for diffractive optical elements that consist of features ranging from subwavelength to more than 10lambda. The essence of the method is treating local structures of the optical elements as diffraction gratings. It is shown that the method can provide accuracy of results comparable with fully electromagnetic treatments in much shorter time. The theory and results are explained assuming micro-Fresnel lenses with one-dimensional structures for investigating polarization properties.

In this paper, the optimal Fresnel lenses are designed by Zemax software.The fundamental problem of the Fresnel lenses is the beam divergence, which wasresolved by decreeing the output stain diameter on the image plane. For this purpose,two types of radial and cylindrical Fresnel lenses are simulated with different groovesusing Global and Hammer optimization methods. The minimum output stain di...
متن کامل3-D reconstruction of phase grating via digital micro-holography
Digital micro-holography technique, a combination of digital holography with microscopy, can be used to measure and analyse the micro-structure and status information of samples when the digital hologram registered is reconstructed numerically by some numerical methods based on the principle of scalar diffraction or coherent image. By summarizing the development of digital micro-holography, Fre...
متن کاملMicromachined Vertical Three-Dimensional Micro-Fresnel Lenses For Free-Space Integrated Micro-Optics
We report the first fabrication of vertical three-dimensional micro-Fresnel lenses with polysilicon materials by surface micromachining technique. Micro-Fresnel lenses play a very important role in micro-optics because of their thin film structures and their ability to achieve very short focal lengths. Although micro-Fresnel lenses have been studied and well understood [ 11, the lens planes usu...

Fabricating an electrically switchable cylindrical Fresnel lens based on holographic polymer-dispersed liquid crystals (H-PDLC) using a Michelson interferometer is reported. Simplicity of the method and possibility of fabricating different focal length lenses in a single set up are among the advantages of the method. It is demonstrated that the Fresnel structured zone plate acts as a cylindrica...
متن کاملEvaluation of Levels of Macro- and Micro-Nutrients in Workers Exposed to Electromagnetic Fields and Comparison with Levels of Patients with Leukemia
There have been much speculation and debate concerning the effect of electromagnetic fields (EMF) on body systems. Various reports have implicated excessive exposure to EMF to certain forms of leukemia. It has also been reported that EMF may cause alteration in the levels of certain macro- and micro-nutrients such as copper, zinc, selenium, calcium and iron. We have undertaken this study to det...
