This Roadmap article on digital holography provides an overview of a vast array of research
activities in the field of digital holography. The paper consists of a series of 25 sections from …

Computational methods have been established as cornerstones in optical imaging and
holography in recent years. Every year, the dependence of optical imaging and holography …

Lensless imaging eliminates the need for geometric isomorphism between a scene and an
image while allowing the construction of compact, lightweight imaging systems. However, a …

Femtosecond lasers are powerful in studying matter's ultrafast dynamics within femtosecond
to attosecond time scales. Drawing a three-dimensional (3D) topological map of the optical …

Compressive sensing (CS) is a sub-Nyquist sampling framework that has been employed to
improve the performance of numerous imaging applications during the last 15 years. Yet, its …

Hyperspectral (HS) imaging involves the sensing of a scene's spectral properties, which are
often redundant in nature. The redundancy of the information motivates our quest to …

This paper is devoted to reviewing the results achieved so far in the application of the single-
pixel imaging technique to terahertz (THz) systems. The use of THz radiation for imaging …

Several hyperspectral (HS) systems based on compressive sensing (CS) theory have been
presented to capture HS images with high accuracy and with a lower number of …

In this Letter, we present a new snapshot hyperspectral (HS) camera based on a multi-
aperture design. The technique uses an array of modified Fabry–Perot resonators together …

We propose a preliminary lensless inference camera (LLI camera) specialized for object
recognition. The LLI camera performs computationally efficient data preprocessing on the …
