本研究主要是照相鏡頭為例,以單波長準直雷射配合模擬軟體進行研究,首先實拍確認成像品質並使用軟體模擬比對雜散光成像、能量和雜散光的準直光之路徑,再依光學模擬角度使用單波長準直雷射光確認路徑並實拍照片分析實拍雜散光能量,以模擬之結果提出更準確的鏡頭雜散光改善方法,改善後再以此系統確認比較改善前後之效果。實驗結果針對雜散光不同的成因改善效果最高可達99%,幾乎在實拍成像上可以看不到Flare之現象。透過此研究,以單波長準直雷射光的應用結合模擬軟體的分析能有效的找出雜散光的產生路徑並將能量量化,且應用模擬找出之雜散光路徑結合適當的製程改善方案或光機結構的設計變更以達到雜散光的抑制,使鏡頭能得到更好的成像品質。
The topic of this research is trying to analyze and improve the stray light of the embedded camera lens unit by applying the Single Wavelength Collimated Laser. First, to review the image quality with the stray light and then simulate the stray light image, energy , and the path of the single straight light. Second, according to optical simulated angle to verify the stray light path by applying the Single Wavelength Collimated Laser. Therefore, we analyzed the stray light energy by the image quality so as to correct the stray light by simulation results which can help us to realize if we can get the better improvement in the system in comparison. According to this research experiment, the result can be used to eliminate almost stray light in the image and improvement yield rate closely to 99%. By this experiment verification we can find out the stray light path and measure the energy which can help us improve the process or change optical /mechanical design to eliminate the stray light to get better image quality.
