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. WebSep 14, 2024 · An optical assembly to enable distortion compensation and enhanced image clarity is provided. The optical assembly may include an optical stack, such as pancake optics. The optical assembly may also include at least two optical elements.

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. WebHolographic optical traps use the forces exerted by computer-generated holograms to trap, move and otherwise transform mesoscopically textured materials. This article introduces methods for optimizing holographic optical traps’ e ciency and accuracy, and an optimal statistical approach for characterizing their performance.
