像散透镜 meaning in English
astigmatic lens
Examples
- Parameter changes of gaussian beams after passing through astigmatic lens
高斯光束通过像散透镜后光束参数的变化 - Based on the generalized huygens - fresnel diffraction integral and in consideration of the effect introduced by astigmatism , the transformation properties of gaussian beams passing an astigmatic lens are studied analytically , the beam quality of astigmatic gaussian beams is analyzed in terms of the beam propagation factor ( m2 - factor ) and power in the bucket ( pib ) , and illustrated with numerical examples
基于广义惠更斯-菲涅尔衍射积分，并考虑了像散的影响，对高斯光束通过像散透镜后的传输特性作了解析研究，以光束传输因子和桶中功率为参数分析了像散高斯光束的光束质量，并以数值计算例加以说明。
