TL;DR: In this article, a fully suspended RGO photodetector is constructed using the free-standing RGO thin film, which exhibits the fastest (ca.100ms) and broadest (from the ultraviolet to terahertz spectral range) photoresponse among all of the reported RGO film photoderectors that have been reported.

TL;DR: This work reports an ultra-broadband bolometric photodetector based on a suspended CNT film that demonstrates a high performance with an ultraviolet responsivity of up to 0.58 A/W with a bias voltage of 0.2 V and a short response time of ∼150 μs in vacuum, which is better than that of many otherPhotodetectors based on CNTs.

TL;DR: In this paper, an x-ray imaging system is used to perform a CT reconstruction of an examined object in a dark-field CT imaging of an object using an imaging system consisting of an xray source, two absorbing gratings, a detector, a controller and a data processing unit.

TL;DR: An X-ray cargo inspection system with few-view projection imaging is developed for detecting contraband in air containers in this paper, including its configuration and the process of inspection using three imaging modalities: digital radiography (DR), few view imaging and computed tomography (CT).

TL;DR: Compressive sensing (CS), which aims at sparse sampling, is extended to direct MMW holographic imaging for reducing the number of antenna units or the data acquisition time and the feasibility of recovering MMW images from measurements at 1/2 or even 1/4 of the Nyquist rate is demonstrated.
