“…Different from the coherent imaging system [11,12], an incoherent optical system such as a single-pixel imaging (SPI) system [16][17][18][19][20][21] will have significantly lower experimental complexity. In fact, this has been revealed in some previous works about optical computing [22] and holography [23]. The object image is usually captured by a pixelated sensor array in a conventional optical imaging system.…”

Two novel visual cryptography (VC) schemes are proposed by combining VC with single-pixel imaging (SPI) for the first time. It is pointed out that the overlapping of visual key images in VC is similar to the superposition of pixel intensities by a single-pixel detector in SPI. In the first scheme, QR-code VC is designed by using opaque sheets instead of transparent sheets. The secret image can be recovered when identical illumination patterns are projected onto multiple visual key images and a single detector is used to record the total light intensities. In the second scheme, the secret image is shared by multiple illumination pattern sequences and it can be recovered when the visual key patterns are projected onto identical items. The application of VC can be extended to more diversified scenarios by our proposed schemes.

“…However, to reduce the inherent problem of speckle noise, incoherent techniques have also been developed. There are two main techniques to obtain incoherent holograms [8]. The first is the Optical Scanning Holography (OSH) that employs a laser light source during the acquisition process.…”

“…The first is the Optical Scanning Holography (OSH) that employs a laser light source during the acquisition process. Despite the light source being coherent, the acquired hologram can be incoherent: this feature depends on the acquisition geometry [8,9]. The other technique is called Fresnel Incoherent Correlation Holography (FICH), and in this case the light source can be incoherent (such as the sunlight) [8,10].…”

Digital holography represents a novel media which promises to revolutionize the way the users interacts with content. This paper presents an in-depth review of the state-of-the-art algorithms for advanced processing and rendering of computer-generated holography. Open-access holographic data are selected and characterized as references for the experimental analysis. The design of a tool for digital hologram rendering and quality evaluation is presented and implemented as an open-source reference software, with the aim to encourage the approach to the holography research area, and simplify the rendering and quality evaluation tasks. Exploration studies focused on the reproducibility of the results are reported, showing a practical application of the proposed architecture for standardization activities. A final discussion on the results obtained is reported, also highlighting the future developments of the reconstruction software that is made publicly available with this work.

“…Various techniques have been developed to expand the applications of incoherent holography [1][2][3][4]. These techniques include using a spatial light modulator [5,6], a concave mirror [7], radial shearing [8], and rotational shearing [9] in the interferometric systems, and are based on diffraction theory and the self-interference principle [10].…”

We propose a technique of multispectral incoherent holography. The differential wavefront curvature is measured, and the principle of Fourier transform spectrometry is applied to provide a set of spectral components of three-dimensional images and continuous spectra for spatially incoherent, polychromatic objects. This paper presents the mathematical formulation of the principle and the experimental results. Three-dimensional imaging properties are investigated based on an analytical impulse response function. The experimental and theoretical results agree well.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.
