“…The so-called Paganin method (PM) [51] has been particularly successful in this regard, with acquisition-time-reductions in the tens of thousands being typical [50], [52], [53], [54], [55]. While phase contrast has been incorporated into visible-light GI protocols through the use of interferometers [56], [57], [58], [59], these are difficult to translate to an X-ray setting. Indeed, the standard X-ray GI setup is totally insensitive to any refractive effects (phase shifts) imparted by the sample since such effects have no influence on the total number of photons registered in each bucket measurement.…”

Ghost imaging has recently been successfully achieved in the X-ray regime; due to the penetrating power of X-rays this immediately opens up the possibility of X-ray ghost tomography. No research into this topic currently exists in the literature. Here we present adaptations of conventional tomography techniques to this new ghost imaging scheme. Several numerical implementations for tomography through X-ray ghost imaging are considered. Specific attention is paid to schemes for denoising of the resulting tomographic reconstruction, issues related to dose fractionation, and considerations regarding the ensemble of illuminating masks used for ghost imaging. Each theme is explored through a series of numerical simulations, and several suggestions offered for practical realisations of Xray ghost tomography.

“…As a result, the SPCs have been successfully applied in many different imaging areas during the last decade. Among them, we can mention infrared imaging [17,18], terahertz imaging [19], ultrasonic imaging [20], 3D computational imaging [21,22], imaging through scattering media [23][24][25], 3D and photon counting light detection and ranging (LIDAR) imaging systems [3,26,27], stereoscopic imaging [28], microscopy [29,30], holography [31,32], and ophthalmoscope imaging [33].…”

Single-pixel cameras (SPCs) have been successfully used in different imaging applications during the last decade. In these techniques, the scene is illuminated with a sequence of microstructured light patterns codified onto a programmable spatial light modulator. The light coming from the scene is collected by a bucket detector, such as a photodiode. The image is recovered computationally from the photodiode electric signal. In this context, the signal quality is of capital value. One factor that degrades the signal quality is the noise, in particular, the photocurrent, the dark-current, and the thermal noise sources. In this chapter, we develop a numerical model of a SPC based on a photodiode, which considers the characteristics of the incident light, as well as the photodiode specifications. This model includes the abovementioned noise sources and infers the signal-to-noise ratio (SNR) of the SPCs in different contexts. In particular, we study the SNR as a function of the optical power of the incident light, the wavelength, and the photodiode temperature. The results of the model are compared with those obtained experimentally with a SPC.

“…A number of computational correlation techniques are proposed, such as computational ghost imaging [26,27], single-pixel imaging [28][29][30]. Methods to retrieve the complex field under single pixel detection are proposed by structured mask illumination [31][32][33].…”

We propose a new scheme for the recovery of complex-valued objects in a single-pixel hybrid correlation holography. The idea is to generate an intensity correlation hologram from the correlation of intensity fluctuations obtained over two channels, namely an optical channel equipped with a single pixel detector and a digital channel. The scheme has a theoretical basis which is described to reconstruct the objects from a single pixel detector. An experimental arrangement is proposed and as a first step towards realizing/implementing the technique, simulation of the experimental model was carried to image three complex objects.
