WebSep 5, 2014 · The 3D object can be reconstructed at a designed distance behind the volume holographic polymer by illuminating with the reference beam. Volume holographic kinoform can realize high-resolution... WebThe optical properties of holographic kinoforms are described. It is shown that paraxial designs are not adequate for f-numbers less than approximately F/10. A non-paraxial design is introduced which retains the high diffraction efficiency of the paraxial designs, yet also produces a non-aberrated diffracted wavefront for the design wavelength.

Applications and modeling of diffractive optical elements

WebDiffractive optics technology provides a new approach to optical design and fabrication using computer-aided design tools and integrated circuit manufacturing methods. With this approach, one creates an efficient holographic element in the form of a surface relief profile etched into an optical substrate. WebBy sidestepping the requirements for high-performance light sources, switching optics, or delicate alignment, this approach points toward ultracompact and cost-effective … WebDynamic holographic optical tweezers need not be limited to planar configurations. If the laser beam illuminating the SLM were slightly diverging, then the entire pattern of traps would come to a focus downstream of the focal plane. Such divergence can be introduced with a Fresnel lens, encoded as a phase grating with. how much is great america gold pass
