Abstract

在同一单色平行光源照射下研究微孔通道深度与宽度比值、球面曲率半径对观测视场、空间分辨率和光学灵敏度等成像指标的影响.结果表明:随着微孔通道深度与宽度比值的增加,空间角分辨能力逐渐变强,像面总光强逐渐变弱,在比值达到25∶1时,聚焦光线有效面积达到最大值;在同一微孔尺寸下,元件曲率半径的变化对空间角分辨率影响较小,更大的曲率半径有更大的有效面积,但同时要求更大的元件体积.

Other Abstract

The influence of micro-channel ratio of length to width and radius of curvature on imaging of lobster-eye optical system under the same parallel monochromatic light source condition was investigated.The results show that with the increase of the micro-channel ratio of length to width,the angular resolution becomes better while the total intensity of image surface decreases gradually.When the ratio reaches 25∶1,the effective area of focused X-rays reaches the maximum value.Under same microchannel size condition,the change of radius of curvature has less influence on angular resolution,and the larger radius brings the larger effective area,but requires larger element volume for same field of view at the same time.
