| 摘 要： | 小型固化光学相关器,以偏振分光棱镜和反射型傅里叶透镜作为基本部件,并采用透明固体介质填充光学系统的空隙。该系统通过各元件端面相连,简化了校准难度;使用反射型透镜,具有色像差和轴外像差小的优势。模拟分析表明,这种固化结构具有良好的系统性能,并满足识别的需要。

Solidification design and performance analysis of an optical correlator system |
| |
| Abstract: | A miniature solidified optical correlator is constructed by taking polarization splitting prism and reflection type Fourier lens as basic components. The gaps of optical system is filled with transparent solid medium. The calibration difficulty of the optical system is simplified through connecting end faces of various elements. The use of the reflection type lens makes the system have superiority of less chromatic aberration and off-axis aberration. Simulation analysis shows that this solidified structure has high performance and can meet the demand for recognition task. |
