Ray tracing through Fresnel zone plate.
Journal of the Spectroscopical Society of Japan, 1987 Simple equations for tracing rays through the Fresnel zone plate have been derived. The spot diagram constructed by means of the ray tracing shows an appearance of imagery of the Fresnel zone plate as a focusing element. The spot diagram can be obtained not only for the real images but also for the imaginary images.

Advanced Optical Materials, Volume 14, Issue 14, 10 April 2026.Possibilities for ablation‐free microforming of borosilicate glass using ultrashort laser pulses are presented. Depending on the laser parameters and scanning strategy, surface structures with profile heights of up to 20 µm could be produced. The work provides a comprehensive experimental and analytical characterization of the microforming process ...

Implementation and Verification of Fresnel Zone Plate Patterns Designed by Optimization of Surface Phase [PDF]
한국정밀공학회지In this study, we present a numerical simulation approach for designing Fresnel zone plate (FZP) patterns. By optimizing surface phase parameters using desired merit functions in ray-tracing software, the obtained surface phase was converted into an FZP ...

Advanced Science, Volume 13, Issue 22, 17 April 2026.A functionally driven variable‐cell size and gradient‐conductive coated TPMS structure was developed. Accordingly, stepwise longitudinal gradient impedance was realized, achieving absorption‐dominant EMI shielding (absorptivity≈0.85) with an EMI SET of ≈ 59 dB, for 10 mm‐thick composites. Further increasing the thickness of composites to 20 mm achieved

Multiple-wave radial shearing interferometer based on a Fresnel zone plate.
Optics Express, 2018 A compact multiple-wave radial shearing interferometer (MWRSI) with strong adaptability, which is based on a Fresnel zone plate (FZP), is proposed. The nominally plane beam under test passes through the FZP and diffracts into multiple orders, including ...
