“…Sinusoidal fitting of the 8 th order is selected in this experiment because this curve fitting is closest to the ideal with good fitting values. The fitness parameters obtained for the transmission (%) and absorbance (𝐴𝑢) are tabulated in Table (5). From the fitting parameters, it is observed that the value of R-square is close to unity for both transmission (%) and absorbance (𝐴𝑢).…”

In this research work, a low-cost \(UV-Vis-NIR\) spectroscopy setup (\(LCSS\)) is developed and presented to analyze transmission (%) and absorption (\(Au\)) from household oils samples. The sensing potential of the developed setup is examined using four different oil samples. These oil samples consist of olive oil, mustard oil, amla oil, and red palm oil. The transmission (%) obtained for olive oil, mustard oil, amla oil, and red palm oil is \(75.66\%\), \(71.10\%\), \(69.87\%\), and \(68.12 \%\) at \(923.2 nm\), \(924.5 nm\), \(925.9 nm,\) and \(927.8 nm\) respectively. Similarly, the absorbance (\(Au\)) for olive oil, mustard oil, amla oil, and red palm oil is \(0.121 Au\), \(0.141 Au\), \(0.153 Au,\) and \(0.163 Au\) at \(920.0 nm\), \(923.0 nm\), \(925.8 nm\), and \(930.2 nm\) respectively. A linear relationship in the wavelength range of \(920 nm\) to \(935 nm\) between transmission (%) and wavelength produce \({R}^{2}=0.9717\) corresponding to a degree (2). Similarly, the linear relation between absorbance (\(Au\)) and wavelength produce \({R}^{2}=0.9997\) corresponding to a degree (2). Finally, an 8th order empirical sinusoidal model is developed for transmission (\(\%\)) and absorbance (\(Au\)) corresponding to the olive oil, mustard oil, amla oil, and red palm oil. The maximum value of \(R-\)square corresponding to the transmission (\(\%\)) for the developed empirical model is obtained for amla oil. Similarly, the full value of the absorbance (\(Au\)) from the developed empirical model is obtained for red palm oil, which indicates a great response towards the empirical sinusoidal model.

“…The numerical simulations reflect the influences factors for propagating includes the beam topological charge, the beam waist, the wavelength and the turbulent strength [4]. Therefore, if we can achieve sufficient Monte Carlo experiments, the phase screen sample sets are able to reflect the atmospheric turbulence state [5]. A large number of experimental samples is necessary to ensure the correctness of the parameters.…”

In this paper, a novel recognition method based on random matrix is proposed for different turbulence intensity. To reflect the degree of atmospheric turbulence, the continuous product form of phase screens is taken into consideration. After calculated the statistical distribution using random matrix theory, the fitting effect of statistical distribution determines the differences of turbulence. Also, based on the data-driven idea, the eigenvalue and singular values of phase screens are described as a whole. According to the adaptability of large dimensional random matrices, the Ring Law and M-P Law breaks through the assumptive restriction of infinite sample, thus building a significant model for potential changes of weak turbulence. The simulation experiments validate that the big data technology is effective attempt for atmospheric turbulence recognition.

“…These test systems and improved test methods have not changed the problem that the detection performance of photoelectric detection target is affected by the environment. In addition, the laser target with active detection mode is designed in reference [10, 11], and the detection field of view of the laser target is affected by its frame structure, so it has not been widely used in the test field of weapon range. In order to expand the detection field of view and stabilize the detection ability of traditional photoelectric detection target, a design method of laser photoelectric detection sensor is proposed in this paper.…”

In order to solve the problem of unstable detection and low detection ability of traditional photoelectric detection target in complex environment, a design method of laser photoelectric detection sensor is proposed. Laser photoelectric detection sensor with active and passive laser detection screen is formed by adding line laser to the traditional photoelectric detection target. According to the characteristics of laser echo energy when the projectile passing through the laser detection screen, the calculation model of the laser echo power received by the photoelectric detector under the random intersection of projectile and target is established, and the signal‐to‐noise ratio calculation function of the system is derived. Through the comparative test, the results show that the detection ability of the laser photoelectric detection sensor is obviously better than that of the traditional photoelectric detection target, especially in the low illumination environment; moreover, the signal‐to‐noise ratio of the laser photoelectric detection sensor still follows the law of decreasing with the increase of detection distance, and it keeps the detection characteristics of photoelectric detection system. By increasing the laser emission power, the signal‐to‐noise ratio of the laser photoelectric detection sensor is improved to a certain extent, and the detection ability of the system is improved. The results verify that the design method and theoretical model of photoelectric detection sensor proposed in this paper are scientific and feasible.
