WebMay 15, 2024 · A model that considers the recording material's response, by determining the index modulation reached for each spatial frequency and exposure dosage, has been developed and has been validated with experimental measurements of three cylindrical holographic lenses with different spatial frequency ranges recorded in Bayfol HX … WebIn the method, the pre-magnification recording geometry is realized by a cylindrical lens (CL) or cylindrical beam instead of a conventional objective or spherical beam in traditional off-axis digital holography (DH). At the same time, the reference beam is replaced by a divergent cylindrical beam.
