Staring from Fresnel diffraction integral,we deduced the optical intensity distribution in the Fresnel zone of the diffraction field of the annular-aperture lens axicon.
结果表明,光谱半宽σ小的多色高斯光束照射透镜轴棱锥时,不同观察面的光强分布均为J20的形式。
In this paper, a new method for image stabilization with a three-axis image-stabilizing reflecting prism assembly is presented, and the principle of image stabilization in this prism assembly, formula for image stabilization and working formula with an approximation up to the third power are given in detial.
提出了用三轴稳像棱镜组进行图像稳定的新方案,并给出了较详细的理论分析、稳像公式和三阶近似的工程稳像公式。
On the basis of analyzing the three-axis image-stabilizing reflecting prism assembly,this paper presents a method for image-stabilizing with the prism assembly and scanning with the other optcal elements.
本文在对三轴稳像棱镜组研究的基础上，提出了用三轴稳像棱镜组进行稳像，用另外的扫描部件作扫描的方案。
