“…FOV multiplexing can also be employed in common-path multi-beam interferometry with small shearing 199 – 202 . The hybrid amplitude cross-checker 203 and randomly encoded 204 gratings recently emerged as diffraction-efficient approaches. The diffraction grating profile determines the multibeam interference angles, hence enabling the tailoring in the k -space of the hologram.…”

In 1948, Dennis Gabor proposed the concept of holography, providing a pioneering solution to a quantitative description of the optical wavefront. After 75 years of development, holographic imaging has become a powerful tool for optical wavefront measurement and quantitative phase imaging. The emergence of this technology has given fresh energy to physics, biology, and materials science. Digital holography (DH) possesses the quantitative advantages of wide-field, non-contact, precise, and dynamic measurement capability for complex-waves. DH has unique capabilities for the propagation of optical fields by measuring light scattering with phase information. It offers quantitative visualization of the refractive index and thickness distribution of weak absorption samples, which plays a vital role in the pathophysiology of various diseases and the characterization of various materials. It provides a possibility to bridge the gap between the imaging and scattering disciplines. The propagation of wavefront is described by the complex amplitude. The complex-value in the complex-domain is reconstructed from the intensity-value measurement by camera in the real-domain. Here, we regard the process of holographic recording and reconstruction as a transformation between complex-domain and real-domain, and discuss the mathematics and physical principles of reconstruction. We review the DH in underlying principles, technical approaches, and the breadth of applications. We conclude with emerging challenges and opportunities based on combining holographic imaging with other methodologies that expand the scope and utility of holographic imaging even further. The multidisciplinary nature brings technology and application experts together in label-free cell biology, analytical chemistry, clinical sciences, wavefront sensing, and semiconductor production.

“…These were the foundations of several works with new RR and bRR patterns, for example in Arriaga et al [20], where a mask was built to induce a periodicity, in the application of the Shack-Hartmmann wavefront technologies in spectacle lenses sensing, as in the work by Yu et al [21] and in the comparison of results using ophthalmological elements as in the work by Jia et al [22]. The bRR were also analyzed as diffractive elements considering their properties and viability in the surface sensing as performed by Toto et al [23]; in the work by Cordero et al [24] where a lensometer is proposed for sensing several optical surfaces based on the autocollimation systems' principles, as in the work by Arriaga et al [25] where the projection of the bRR is simulated to reconstruct 3D profiles in micrographies, or in the case of Patorski et al [26], where the diffractive phenomena of several masks are analyzed.…”

In this work, we show a proposal involving differential and vectorial equations to obtain the scalar surface of a wavefront (W) and the transversal aberration (TA) from the Bi-Ronchi test (BRT). The execution and computation times of this technique are significantly lower than those corresponding to the Ronchi test (RT). Moreover, it provides wavefront results along the axes X and Y by using bi-Ronchi ruling (bRR) with periods in XY. In the case of mirrors, this technique provides complete information of the whole surface along XY from a single test, with the potential to be applied in the other optical elements to measure their wavefronts. Hence, we propose the construction of square meshes, bRR type meshes, using Al and Au atomic depositions in glass substrates with different periods in XY, allowing us to observe bi-Ronchigrams. The captures of Bironchigrams enabled us to perform the analysis of the transversal aberrations in terms of the Zernike polynomials described by circular polynomials and an angular function with respect to the azimuthal term. We build a matrix solution from the vectors used to identify the centroids in the bi-Ronchigram higher-intensity zones, also considering the Rayces’ equations from which the wavefront and the transversal aberrations are simultaneously obtained. We discuss and compare our results with the RT. Finally, we highlight an additional result related to the proposed technique, involving the contention of the Ronchigram in the Bi-Ronchigram, resembling the case where the BRT contains the RT.

Off-axis digital holographic multiplexing for rapid wavefront acquisition and processing

et al. 2020

Off-axis holographic multiplexing involves capturing several complex wavefronts, each encoded into off-axis holograms with different interference fringe orientations, simultaneously, with a single camera acquisition. Thus, the multiplexed off-axis hologram can capture several wavefronts at once, where each one encodes different information from the sample, using the same number of pixels typically required for acquiring a single conventional off-axis hologram encoding only one sample wavefront. This gives rise to many possible applications, with focus on acquisition of dynamic samples, with hundreds of scientific papers already published in the last decade. These include field-of-view multiplexing, depth-of-field multiplexing, angular perspective multiplexing for tomographic phase microscopy for 3-D refractive index imaging, multiple wavelength multiplexing for multiwavelength phase unwrapping or for spectroscopy, performing super-resolution holographic imaging with synthetic aperture with simultaneous acquisition, holographic imaging of ultrafast events by encoding different temporal events into the parallel channels using laser pulses, measuring the Jones matrix and the birefringence of the sample from a single multiplexed hologram, and measuring several fluorescent microscopy channels and quantitative phase profiles together, among others. Each of the multiplexing techniques opens new perspectives for applying holography to efficiently measure challenging biological and metrological samples. Furthermore, even if the multiplexing is done digitally, off-axis holographic multiplexing is useful for rapid processing of the wavefront, for holographic compression, and for visualization purposes. Although each of these applications typically requires a different optical system or processing, they all share the same theoretical background. We therefore review the theory, various optical systems, applications, and perspectives of the field of off-axis holographic multiplexing, with the goal of stimulating its further development.
