- 中文摘要: 在本文中,我們提出低階純相位圓諧濾波法和高階圓諧濾波法的一些光學實驗結果,並加以比較。光學實驗中所用之濾波片為電腦全像片(是二元的電腦全像片),實驗之光路為標準的傅氏轉換光學系統。實驗結果符合電腦模擬的結果,即低階的純相位圓諧濾波法所產生的旁葉(Side-lobe)比高階圓諧濾波法較小,並且在同樣條件下,低階純相位圓諧濾波法所產生的相關峰值(Correlation peak)也比高階圓諧濾波法的峰值強。
- 英文摘要: Optical experimental results of low order phase-only circular harmonic filtering and high order ordin-ary circular harmonic filtering using binary computer generated holograms in a standard Fourier transformcorrelator are presented here. The experimental results have corroborated the computer simulation thatlow order phase-only circular harmonic filtering produces a smaller side-lobe than does high order ordinarycircular harmonic filtering, and that the correlation peaks produced by low order phase-only circular bar-monic filtering are stronger than those yielded by high order ordinary circular harmonic filtering undersimilar conditions.
