中文摘要:分块式平面光电探测成像技术(Segmented Planar Imaging Detector for Electro-optical Reconnaissance,SPIDER)是基于干涉原理的新型光电成像技术,其先利用含波导结构的光学系统对物面目标进行空间频域相干采样,然后经图像处理对频域图像进行傅里叶逆变换,从而恢复目标图像。深入研究了SPIDER成像技术的成像原理、实现方法以及结构参数对SPIDER成像系统的影响机制,并在此基础上完成了波长在1.5 μm~1.9 μm范围的成像仿真验证。结果表明,SPIDER成像技术具有良好的成像效果。

Study of Segmented Planar Imaging Detector for Electro-optical Reconnaissance
Abstract:Segmented Planar Imaging Detector for Electro-optical Reconnaissance (SPIDER) is a new type of electro-optical imaging technology based on the principle of interferometric imaging. First, it utilizes the optical system with a waveguide structure to coherently sample the object in a spatial frequency domain. Then, it uses an image-processing module to restore the object image through inverse Fourier transform in the frequency domain. Its imaging principle, implementation and the influence of structure parameters on imaging are deeply studied. On this basis, the simulation verification of imaging in the wavelength range from 1.5 μm to 1.9 μm is completed. The results show that the segmented planar imaging detector for electro-optical reconnaissance has a good imaging effect.
