“…The frequency selection scheme in this paper is compared with studies in the field of coherent light [16][17][18][22][23][24][25][26][27], where a multiplexed holography scheme for coherent light projects two interferometric patterns with different stripe orientations onto the camera, each capturing a different region of the sample or a complex wave front of a different sample. This technique is called interferometry with double imaging area.…”

We propose a new incoherent optical holographic spectrum stripping reconstruction method, called incoherent multiplexing frequency-selective holography, which compresses two or more on-axis holograms into a single multiplexed on-axis hologram without loss of magnification and resolution. The technique described in this chapter effectively suppresses the background bias term and conjugate term. The acquired spectrum is obtained by stripping in the overlapping confounding correlation terms. The experimental results show the potential of the method in areas such as compressed holography and extended field of view imaging.

“…Spatial light modulators (SLMs) deflect a wave without mechanical motion by directly acting on the wavefront phase of the illuminating beam, effectively allowing for beam angular scanning [ 89 , 90 , 91 , 92 , 93 ], or on the detected field [ 94 ]. Such systems are, however, slower than the fastest resonant galvanometric mirrors.…”

“…However, a better filling of the Fourier space is obtained with more elaborate scanning patterns [ 72 , 183 , 184 , 185 ] (note that the demonstration of the existence of an optimal scanning scheme, as well as its exact determination are still to be performed). The preprocessing of the holograms [ 52 , 186 ], or the implementation of adaptive illumination [ 91 ], for example, to correct for residual aberrations, as well as data sorting to suppress bad-quality data [ 187 , 188 ], also help to maintain a good image quality while trying to minimize the volume of acquisitions.…”

Optical microscopy techniques are among the most used methods in biomedical sample characterization. In their more advanced realization, optical microscopes demonstrate resolution down to the nanometric scale. These methods rely on the use of fluorescent sample labeling in order to break the diffraction limit. However, fluorescent molecules’ phototoxicity or photobleaching is not always compatible with the investigated samples. To overcome this limitation, quantitative phase imaging techniques have been proposed. Among these, holographic imaging has demonstrated its ability to image living microscopic samples without staining. However, for a 3D assessment of samples, tomographic acquisitions are needed. Tomographic Diffraction Microscopy (TDM) combines holographic acquisitions with tomographic reconstructions. Relying on a 3D synthetic aperture process, TDM allows for 3D quantitative measurements of the complex refractive index of the investigated sample. Since its initial proposition by Emil Wolf in 1969, the concept of TDM has found a lot of applications and has become one of the hot topics in biomedical imaging. This review focuses on recent achievements in TDM development. Current trends and perspectives of the technique are also discussed.

“…The trapping beam can be single or multiple based on the design adapted in the CGH and can be dynamically manipulated. The HOT quickly emerged and became indispensable in the field of biology [74][75][76]. An alternate architecture inspired by FINCH polarization multiplexing scheme to the conventional trapping architecture for single beam compact trapping and imaging is shown in Figure 12.…”

Incoherent holographic imaging technologies, in general, involve multiple optical components for beam splitting—combining and shaping—and in most cases, require an active optical device such as a spatial light modulator (SLM) for generating multiple phase-shifted holograms in time. The above requirements made the realization of holography-based products expensive, heavy, large, and slow. To successfully transfer the holography capabilities discussed in research articles to products, it is necessary to find methods to simplify holography architectures. In this book chapter, two important incoherent holography techniques, namely interference-based Fresnel incoherent correlation holography (FINCH) and interferenceless coded aperture correlation holography (I-COACH), have been successfully simplified in space and time using advanced manufacturing methods and nonlinear reconstruction, respectively. Both techniques have been realized in compact optical architectures using a single static diffractive optical element manufactured using lithography technologies. Randomly multiplexed diffractive lenses were manufactured using electron beam lithography for FINCH. A quasi-random lens and a mask containing a quasi-random array of pinholes were manufactured using electron beam lithography and photolithography, respectively, for I-COACH. In both cases, the compactification has been achieved without sacrificing the performances. The design, fabrication, and experiments of FINCH and I-COACH with static diffractive optical elements are presented in details.
