| dc.description.abstract | 在Shack-Hartmann 波前感應器的資料處理中，正確地把光點分配到各個微透鏡是非常重要的。傳統的分配算法的限制斑點的量轉移到微透鏡的直徑的一半，從而限制了Shack Hartmann感應器的動態範圍。
這項工作提出了擴展的動態範圍的Shack-Hartmann波前感應器的質量引導演算法。該算法提供了高動態範圍，並且準確度不受局部缺陷及光點遺失的影響。
該演算法經由模擬的Shack-Hartmann點和實驗獲得的Shack-Hartmann點做測試，並與現有的演算法相比。我們對模擬結果和實際情況的數據進行了分析，並對它們之間的差異進行了討論。 | zh_TW |
| dc.description.abstract | Assignment of spots to the correct lenslet is critically important to a Shack Hartmann wavefront sensor. Conventional assignment-algorithm limits the amount of spots shift to be half the lenslet diameter, thereby limiting the dynamic range of the sensor.
This work presents a quality-guided algorithm to extend the dynamic range of a Shack-Hartmann wavefront sensor. The proposed algorithm offers a high dynamic range and excellent robustness.
The algorithm is tested on both simulated Shack-Hartmann spots and experimentally captured Shack-Hartmann spots.. The performance of the proposed algorithm is compared with existing algorithms. Results from simulation and from real-case data are analyzed. Any discrepancies are discussed. | en_US |
