摘要

本研究提出了一种利用基尔霍夫近似的相干探测模型，考虑了目标材料的影响。理论分析比较了铜、锌和铁的检测性能，并检验了不同粗糙度和入射角对铁的影响。实验结果证实，铜的信号最强，铁的信号最弱。信号强度稳定在一定的粗糙度水平，增加入射角降低信号强度，峰值向右偏移。该模型的理论和实验结果一致，显著提高了相干检测精度。

The impact of material properties and surface roughness on coherent detection

This study presents a coherent detection model using the Kirchhoff approximation, accounting for the effect of target materials. Theoretical analyses compared detection performance for copper, zinc, and iron, and examined the effects of varying roughness and incident angles on iron. Experimental results confirmed that copper had the strongest signal and iron the weakest. Signal intensity stabilized at a certain roughness level, and increased incident angles reduced intensity and shifted the peak to the right. The model's theoretical and experimental results align, significantly enhancing coherent detection accuracy.

期刊介绍： Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods. Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following: -Optical Metrology- Optical Methods for 3D visualization and virtual engineering- Optical Techniques for Microsystems- Imaging, Microscopy and Adaptive Optics- Computational Imaging- Laser methods in manufacturing- Integrated optical and photonic sensors- Optics and Photonics in Life Science- Hyperspectral and spectroscopic methods- Infrared and Terahertz techniques
