A position detector and 3 beams of ray are used to measure the prismatic, spherical and astigmatic powers.(提出一種眼鏡度數測量方法，利用位置探測器和3條光線實現對棱鏡度、球鏡度和散光度等鏡片參數的測量。)

In view of the above, the transformation properties of astigmatic elliptic Gaussian beams are analysed overall, the exact formulas of correcting astigmatism and rotary symmetrize transformation.(分析像散橢圓高斯光束的傳輸變換特性，推導出半導體激光束的像散校正與旋轉對稱化變換公式。)

These results afford some references for the design and analysis of complex astigmatic cavities.(這一結果對復雜像散腔的設計與分析提供了很好的依據。)

The astigmatic microstructures and condensing microstructures are radial arranged on out-light surface or in-light surface of the board.(散光微結構區及聚光微結構區間隔排列的設置于板體的出光面或入光面上。)

OBJECTIVE: To observe the visual acuities, complications in and after surgery, the astigmatic after the foldable Iol implantation.(前言：目的：觀察折疊人工晶體植入的視力，術中、術后并發癥、術后散光發生。)

Taking a laser beam of astigmatic aberration as an example, the state of the laser beam compensating system can be given by the axial hologram of the laser beam.(我們以象散光束為例，根據軸向全息圖能夠給出該光束補償系統的狀態。)

The results show that the annular beams become non-rotational symmetric after passing through an astigmatic lens.(研究結果表明：環狀光束通過像散透鏡后變為非旋轉對稱光束；)

In chapter 3, the orbital angular momentum of complex astigmatic elliptical beams is investigated.(第三章研究了復雜像散橢圓光束的軌道角動量。)

Astigmatic microstructures contain several cambered surface transmission microstructures, each of the cambered surface transmission microstructures possess an arc convex surface.(散光微結構區包含數個弧面透光微結構，每一弧面透光微結構具有圓弧凸面。)

RESULTS: The results of diopter and astigmatic axis by retinoscopy and computer optometry were same or similar, with no significant difference(P>0.05).(結果：正常瞳孔下電腦驗光和散瞳下檢影驗光得到的屈光度和散光軸向相同或極其相似，統計學處理無顯著性差異（P>0.05）；)
