“…Using the spatial light modulator (SLM) or digital micro-mirror device (DMD) [25] and taking the advantages of the sparsity of the signal, SPI can recover the image in a sampling ratio (SR, defined here as the ratio between the number of measurements and the total pixels.) lower than that required by the Shannon-Nyquist sampling theorem [24].…”

“…A common DMD manufactured by Texas Instruments, such as type DLP 7000, can achieve a maximum switching rate of 22 KHz. The PMT can realize a sampling speed of 60 MHz with the aid of the analogto-digital converter, such as the type PXIe-5105 provided by National Instruments [24]. Consequently, after each excitation, the PMT can record more than 2000 points on the decay curve of the luminescence.…”

“…Single pixel imaging (SPI) is a novel imaging scheme based on the theory of the compressed sensing (CS) [22][23][24].

Temperature- and pressure-sensitive paints (TSPs/PSPs) are the coatings containing luminescent molecules and sensitive to the temperature and oxygen concentration. This work proposed a single-pixel imaging modality of TSPs/PSPs, which can reconstruct the two-dimensional distribution of the lifetime using the signals acquired by a cost-effective photomultiplier tube. A hybrid algorithm was developed as well to solve the resulting inversion problem. Simulative studies have been conducted to validate and assess the performance of the imaging technique under different parameters including the number of sampling points for each illumination, sampling ratio (SR) and noise level in terms of mean square error, mean relative error (MRE) and computational time. Increasing both the number of sampling points and SR would improve the accuracy but takes more computational time. In the cases of the SR equals to 0.8, the MREs are approximately less than half of the noise level.

Combustion diagnostics play an essential role in energy engineering, transportation, and aerospace industries, which has great potential in combustion efficiency improvement and polluting emission control. The three-dimensional (3D) visualization of the combustion field and the measurement of key physical parameters such as temperature, species concentration, and velocity during the combustion process are important topics in the field of combustion diagnostics. Benefiting from the non-contact and non-intrusive advantages of the optical detection method as well as the advantages of the 3D full-field measurement of the measured field by computational tomography, flame chemiluminescence tomography (FCT) has the ability to realize non-intrusive and instantaneous 3D quantitative measurement and 3D full-field visualization of key physical parameters in the combustion process, which has crucial research significance in combustion diagnostics. In this study, we review the progress of FCT technique. First, we provide an extensive review of practical applications of FCT in state-of-the-art combustion diagnostics and research. Then, the basic concepts and mathematical theory of FCT are elaborated. Finally, we introduce the conventional reconstruction algorithm and proceed to more popular artificial intelligence-based algorithms.

“…Here we quantify the improvement in SNR in a single-pixel imaging (SPI) system [12,13] by utilising the correlations from a photon-pair light source. SPI has been demonstrated at a variety of wavelengths [14][15][16], for high-speed applications [17,18], and performing depth measurements [19]. In SPI a series of patterns are projected onto a target, the total power of the corresponding transmitted or back-scattered light is measured using a single-pixel detector revealing the overlap between the projected pattern and the object [20].…”

Single-pixel imaging with heralded single photons

Traditional remote sensing applications are often based on pulsed laser illumination with a narrow linewidth and characteristic repetition rate, which are not conducive to covert operation. Whatever methods are employed for covert sensing, a key requirement is for the probe light to be indistinguishable from background illumination. We present a method to perform single-pixel imaging that suppresses the effect of background light and hence improves the signal-to-noise ratio by using correlated photon-pairs produced via spontaneous parametric down conversion. One of the photons in the pair is used to illuminate the object whilst the other acts as a temporal reference, allowing the signal photons to be distinguished from background noise. Understanding the noise regime is key to producing higher contrast images using this heralding method.
