초록정보

The holographic pattern recognitions of all the Korean alphabets (14 consonants and 10 vowels), characters and words are carried out by using the matched spatial filters. Image reconstructions of the Fourier transform holograms are achieved. By using multiple spatial filter, identification of the unknown character is achieved and the method of simultaneous identifications of all the characters in a page by spatial grouping is also exploited. Enhanced discrimination of an alphabet from those containing it is achieved by using the holographic matched filter prepared from the pseudo-object. It is found that the filter thus prepared gives much reduced cross-correlation signal, without affecting the pattern recognition signal which is the autocorrelation peak signal. The present pseudo-object method is extended to the recognition of the Korean alphabet is often contained in others. The present coherent optical pattern recognition work has proved to be the solutions to the some basic difficulties inherent in the laser analogue communication of the Korean alphabets, characters and words.
