1) In this paper, two methods of realizing optical pattern recognition, spatial matched filter correlation and joint transform correlation(JTC), were discussed first with the emphasis on the JTC.
2) Optical pattern recognition makes an important way to realize the 3D object recognition. It has a huge application and economic value in the social and military domains.
3) Optical pattern dynamics is mainly divided into two parts: laser pattern dynamics and pattern dynamics in optical resonator with nonlinear material.
4) Because of the inherent feature of optical pattern recognition, it is quite difficult to realize target recognition in natural background.
5) The serial encoding method can reduce the diameter of the code disk and simplify the optical pattern,(http://sentencedict.com/optical pattern.html) in favour of miniaturization and high precision of the absolute encoder.
6) By using the computer simulation technique, the theoretical error inthe photodetection process of an optical pattern is correcting.
7) Compared with the traditional absolute optical encoder, the presented encoder has fewer code tracks and a simpler optical pattern, in favour of miniaturization and high precision of absolute encoders.
8) At present, the main pattern recognition includes the computer pattern recognition and the optical pattern recognition.
9) The fractional Fourier transform contains the spatial information and the spatial-frequency information simultaneously. The fractional correlation can be used to optical pattern recognition too.
10) By this filter, the shift, scale and rotation invariant optical pattern recognition was realized with a high signal noise ratio of correlation output.
11) The air flow can adjust the ion distribution and prevent generation of filaments between the electrodes. The different type of applied voltage have great influence on the optical pattern of DBD.
