“…By taking into account space-time duality in optics, the extension of the results of spatial ghost imaging to the time domain has been investigated theoretically, numerically and recently experimentally either with a classical nonstationary light source [9,10], bi-photon states [11], a chaotic laser [12] or a multimode laser source [13]. In all cases, the light emitted by the sources was split into two arms, called "reference" and "test" arms.…”

Ghost imaging is a fascinating process, where light interacting with an object is recorded without resolution, but the shape of the object is nevertheless retrieved, thanks to quantum or classical correlations of this interacting light with either a computed or detected random signal. Recently, ghost imaging has been extended to a time object, by using several thousands copies of this periodic object. Here, we present a very simple device, inspired by computational ghost imaging, that allows the retrieval of a single non-reproducible, periodic or non-periodic, temporal signal. The reconstruction is performed by a single shot, spatially multiplexed, measurement of the spatial intensity correlations between computer-generated random images and the images, modulated by a temporal signal, recorded and summed on a chip CMOS camera used with no temporal resolution. Our device allows the reconstruction of either a single temporal signal with monochrome images or wavelength-multiplexed signals with color images.

“…When the object is illuminated by a light beam with pre-known intensity patterns, the resultant scheme is called CGI or SPC so that the spatially resolved detector are no longer needed [7][8][9][10]. Recently, GI technique has been extended to the time domain by exploiting space-time duality of optics [15], with a classical nonstationary light source [16,17], a chaotic laser [18], biphoton states [19], or a quasi-continuous multimode laser source [20] to produce random illuminations. In [20], a version of the GI protocol creates "temporal" instead of "spatial" images, retrieving an embedded binary signal with a good signal-to-noise ratio (SNR), offering great potential for dynamic imaging of ultrafast waveforms [21].…”

Ghost imaging allows image reconstruction by correlation measurements between a light beam that interacts with the object without spatial resolution and a spatially resolved light beam that never interacts with the object. The two light beams are copies of each other. Its computational version removes the requirement of a spatially resolved detector when the light intensity pattern is pre-known. Here, we exploit the temporal analogue of computational ghost imaging, and demonstrate a computational distributed fiber-optic sensing technique. Temporal images containing spatially distributed scattering information used for sensing purposes are retrieved through correlating the "integrated" backscattered light and the pre-known binary patterns. The sampling rate required for our technique is inversely proportional to the total time duration of a binary sequence, so that it can be significantly reduced compared to that of the traditional methods. Our experiments demonstrate a 3 orders of magnitude reduction in the sampling rate, offering great simplification and cost reduction in the distributed fiber-optic sensors.

“…Shirai et al first proved that temporal ghost imaging with classical pulsed light can be realized by analogy of spatial ghost imaging with thermal light [32]. It was soon realized that temporal ghost imaging can also be performed with entangled photon pairs [33][34][35], chaotic laser light [36,37], and chaotic light [38][39][40]. Recently, computational temporal ghost imaging was also experimentally implemented [41].…”

“…Recently, computational temporal ghost imaging was also experimentally implemented [41]. There are also two light beams in a typical temporal ghost imaging scheme [32][33][34][35][36][37][38][39][40]. The signal beam is modulated by a temporal object and then is detected by a slow detector, which can not follow the variation of the signal.…”

High visibility temporal ghost imaging with classical light is possible when superbunching pseudothermal light is employed. In the numerical simulation, the visibility of temporal ghost imaging with pseudothermal light equaling (4.7 ± 0.2)% can be increased to (75 ± 8)% in the same scheme with superbunching pseudothermal light. The reasons for the difference in visibility and quality of the retrieved images in different situations are discussed in detail. It is concluded that high visibility and high quality temporal ghost image can be obtained by collecting large enough number of data points. The results are helpful to understand the difference between ghost imaging with classical light and entangled photon pairs. The superbunching pseudothermal light can be employed to improve the image quality in ghost imaging applications.
