OPTICAL INFORMATION PROCESSING DEVICE |
摘要 |
PROBLEM TO BE SOLVED: To enable performing various filter processing and picture processing and to make a device compact by obtaining simultaneously not only picture information filtered by a filtering means but Fourier transformation picture information by a picture dividing means and a Fourier transformation information obtaining means. SOLUTION: Picture information previously displayed on a picture display means 13 is read out based on collimation light by a collimation generating means 12. Read out picture information is Fourier-transformed by a Fourier transformation optical system 14. Fourier-transformed picture information is divided into two parts by a picture dividing means 15. One side of divided picture information is taken in by a Fourier transformation information obtaining means 16, while filtering of phase or amplitude information is performed for the other side of picture information by a filtering means 17. Filtered picture information is inverse-Fourier-transformed by an inverse Fourier transformation optical system 18.
