“…To implement a snapshot of 3D images or record 3D movies, a single-shot technique is promising. Although many single-shot techniques have been proposed [13,34,[46][47][48][49][50][51], utilizing dual-phase gratings works with any image sensor in principle, which is useful for optimizing an optical setup with respect to cost, robustness to noise, frame rate, pixel pitch, quantization level, and the number of pixels. By improving light utilization efficiency and reducing the noise, FINCH would be a significant technology for the imaging and measurement community.…”

Fresnel incoherent correlation holography (FINCH) was a milestone in incoherent holography. In this roadmap, two pathways, namely the development of FINCH and applications of FINCH explored by many prominent research groups, are discussed. The current state-of-the-art FINCH technology, challenges, and future perspectives of FINCH technology as recognized by a diverse group of researchers contributing to different facets of research in FINCH have been presented.

“…A recent variant uses a parallel phase-shifting technique to obtain spatially multiplexed phase-shifting holograms simultaneously. 44 A future and logical extension is single photon imaging where each incident photon is recorded in a ultralow-light imaging setup. Albeit the state, the state of research is currently at the numerical simulation stage.…”

“…A demonstration for holographic color acquisitions has been conducted in simulation, using the Shepp-Logan phantom image. 44 In the simple self-interference incoherent digital holography (SIDH), a curved mirror is used to deform the object wavefield so that the interference of this artificially modulated wavefront and the original planar wavefronts is recorded. This self-interference imaging modality is close in concept to differential digital holography where the interference of the wavefront with a shifted version of itself is recorded.…”

Compressed digital holography: from micro towards macro

The age of computational imaging is merging the physical hardware-driven approach of photonics with advanced signal processing methods from software-driven computer engineering and applied mathematics. The compressed sensing theory in particular established a practical framework for reconstructing the scene content using few linear combinations of complex measurements and a sparse prior for regularizing the solution. Compressed sensing found direct applications in digital holography for microscopy. Indeed, the wave propagation phenomenon in free space mixes in a natural way the spatial distribution of point sources from the 3-dimensional scene. As the 3-dimensional scene is mapped to a 2-dimensional hologram, the hologram samples form a compressed representation of the scene as well. This overview paper discusses contributions in the field of compressed digital holography at the micro scale. Then, an outreach on future extensions towards the real-size macro scale is discussed. Thanks to advances in sensor technologies, increasing computing power and the recent improvements in sparse digital signal processing, holographic modalities are on the verge of practical high-quality visualization at a macroscopic scale where much higher resolution holograms must be acquired and processed on the computer.

“…Fresnel incoherent correlation holography (FINCH) is one of the well-established incoherent digital holography techniques [1,2] developed by Rosen and Brooker. In FINCH, the hologram of an object is recorded using the self-interference principle, where both interfering waves are object waves derived from the same object but modulated differently from one another by quadratic phase masks (QPMs) with different focal distances [3][4][5] . Three holograms are recorded in FINCH with pre-calculated phase differences between the two interfering object waves and superimposed to generate a complex hologram.…”

Fresnel incoherent correlation holography (FINCH) is a well-established incoherent imaging technique. In FINCH, three selfinterference holograms are recorded with calculated phase differences between the two interfering, differently modulated object waves and projected into a complex hologram. The object is reconstructed without the twin image and bias terms by a numerical Fresnel back propagation of the complex hologram. A modified approach to implement FINCH by a single camera shot by pre-calibrating the system involving recording of the point spread function library and reconstruction by a nonlinear cross correlation has been introduced recently. The expression of the imaging characteristics from the modulation functions in original FINCH and the modified approach by pre-calibration in spatial and polarization multiplexing schemes are reviewed. The study reveals that a reconstructing function completely independent of the function of the phase mask is required for the faithful expression of the characteristics of the modulating function in image reconstruction. In the polarization multiplexing method by non-linear cross correlation, a partial expression was observed, while in the spatial multiplexing method by non-linear cross correlation, the imaging characteristics converged towards a uniform behavior.
