Laser fuze usually adopt an active detection method, which emits laser pulses to the target through the transmitting system. After scattering by the target, the receiving system obtains the return laser signal. By calculating the time delay between the transmitting pulse and the receiving pulse, the target distance can be calculated. Traditional circular-viewing laser fuze typically use four zones for 360 degree detection, with a detection field angle accuracy of only 90 degrees. In order to achieve accurate measurement of target azimuth angle by laser fuze, this paper proposes a method based on the position of laser spot on a photodetector to calculate the target azimuth angle. The effects of proposed method are analyzed by simulation experiment. The results demonstrate that this method can accurately detect the target azimuth angle.

In recent years, there has been a surge of interest in the development of invisibility cloaks that can manipulate electromagnetic waves. This trend stems from the rapid growth of transformation optics and metamaterials technology, which offers exciting opportunities for controlling light propagation across a broad range of frequencies. One particular type of invisibility cloak that has gained significant attention is the carpet cloak. However, previous implementations of carpet cloaks have encountered limitations that hinder their performance in certain contexts. For example, quasi-conformal mapping carpet cloaks are known to produce a lateral shift in the reflected light ray, leading to undesirable effects in imaging applications. Similarly, birefringent carpet cloaks exhibit polarization dependence, which poses major challenges in situations where polarization may vary. To address these drawbacks, we propose a novel approach using an isotropic non-resonant medium and a judiciously designed conformal mapping to develop a carpet cloak. This design approach overcomes previous limitations by enabling the realization of an invisibility cloak for near-IR. Analytical calculations and numerical simulations are conducted to confirm the polarization-robust performance of this near-IR design, which offers superior performance over prior designs. Furthermore, a microwave carpet cloak design are proposed and verified to prove the universality of this approach. By developing this new approach, we hope to contribute to the advancement of cloaking technology and foster its practical applications in various fields.

In order to further improve the accuracy of quantitative analysis of coal quality by laser induced breakdown spectroscopy (LIBS), the influence of data set partitioning method on quantitative model was studied. The spectral data of 40 different coal samples were collected, and the Support Vector Regression (SVR) model and random forest (RF) model were established by Random Selection (RS), Kennard-Stone (KS) and Sample Partitioning based on joint X-Y distances (SPXY), respectively. The prediction results of ash, volatile matter and calorific value under the two models were compared. The results show that the regression model established by SPXY method combined with RF algorithm has better fitting prediction performance. The predicted root mean square errors (RMSEP) of ash, volatile matter and calorific value are 1.8872, 1.4537 and 0.9020, respectively, and the mean relative errors (MRE) are 6.96%, 3.87% and 2.14%, respectively.

A method of dual-broadband signal generation based on the same optoelectronic oscillator with different tuning mechanisms is proposed in this paper. The structure includes a compatible dual-passband microwave photonic filter based on stimulated Brillouin Scattering effect (SBS) and phase-shifted Bragg fiber (PS-FBG). By implementing the Fourier-domain mode-locked mechanism, the proposed optoelectronic oscillator can simultaneously generate signals in different frequency bands with adjustable center frequency and bandwidth. The effectiveness of the proposed method is verified by experiments. Oscillating signals with bandwidth of 600 MHz and center frequencies at 5 GHz and 6 GHz are generated.

As the requirements of space camera imaging for stability is increasing, on-orbit micro-vibration has become one of the important factors that may affect the imaging of space cameras. The motion forms of space camera caused by micro-vibration were classified, and the mechanisms by which various motions affected the imaging of space camera were analyzed. Considering the effect of optical surface elastic deformation on camera imaging, an integrated model for micro-vibration analysis of space camera was established and the analysis flow was proposed. The integrated analysis model of micro-vibration was applied to the micro-vibration analysis and design improvement of a certain type of space camera, and the analysis results were verified through satellite testing and on-orbit imaging. The verification results show that, the micro-vibration MTF of the space camera is greater than 0.993, and the maximum image motion between the homonymous pixels is less than 1.84 μ m, which meets the requirements of camera imaging.
