삼 분비선의 고정에 미치는 Dimethyl Sulfoxide의 영향
김은수 순천향대학교 1989 논문집 Vol.12 No.4
The infuence of the various fixative on the preservation of the intact ultrastructures was investigated with an electron microscope through the evalution of image quality of glandular trichomes in Cannabis sativa L.(Cannabaceae). The good preservation of the intact cell ultrastructure was observed when the fixation was carried out with 6% glutaraldehyde containing 3% DMSO. However, a lot of secretory material and membrane structures were not examined in the glandular trichomes when 2% acetone was used as a content for the fixative. Although most of the cell organelles of the disc cells which have been respectively fixed with 2% acetone, 3% DMSO and 6% glutaraldehyde were clearer than those of fromer, whole secretory material within the cytoplasm disappeared from the cell.

본 논문에서는 자연광을 이용한 홀로그래픽 3차원 TV시스템을 제안하고 이에 대한 이론적인 전개와 시뮬레이션 그리고 실험결과를 제시하였다. 즉, 기존의 삼각 간섭계에 편광 광분할기, wave plate, 선형편광기 등의 간단한 광학소자를 추가함으로써 바이어스와 공액영상을 제거할 수 있음을 Jones행렬연산을 통해 이론적으로 보였으며, 이를 실험을 통해 입증하였다. 또한 변형된 삼각 간섭계를 이용하여 얻은 복소홀로그램을 효과적으로 표현할 수 있는 시스템을 제안하고 이에 대한 이론적인 전개와 실험을 수행하였다. 본 논문에서 제안된 변형된 삼각 간섭계와 복소홀로그램 재현시스템은 앞으로 홀로그래픽 3차원 입체 TV 시스템의 입력부와 출력부로서 응용이 가능하리라 분석된다. In this paper, a holographic 3-D TV system using natural light, its theoretical analysis, the computer simulation, and some experimental results are presented. In other words, it is theoretically derived by using Jones matrix operation that bias and conjugate image can be removed by adding simple optical components including a plarizing beam splitter, wave plates, and linear polarizers to the conventional Cochran’s triangular interferometer. Also, we suggested a reconstruction system of the complex hologram obtained from the modified triangular interferometer and performed the theoretical analysis and experiment about it. The modified triangular triangular interferometer and the reconstruction system of the complex hologram could be used as input and output systems of the holographic 3-D TV system, respectively.
Hopfield 신경회로망 모델에 의한 광연상 메모리의 실현
김은수 光云大學校 1989 論文集 Vol.18 No.-
Neural network models are receiving increasing attention because of their collective computation capability. In this paper, optical implementation of associative memory based on the modified Hopfield neural network model is described. Numerical and experimental results presented show that the Hopfield neural network model for associative memory fits well the attributes of optics, namely, parallel processing and massive interconnection capabilities. These capabilities allow optical implementation of large neural networks based on the model. Moreover a potentially useful link between neural processing and optics allows the interesting application in pattern recognition and robot vision.
光纖維干涉系를 利用한 Hydrophone 에 關한 硏究
金恩洙 光云大學校 1984 論文集 Vol.13 No.-
In this paper, realizing the fiber-optic hydrophone using the single mode optical fiber interferometer, the acousto-optic effects of optical fiber have been theoretically analyzed and verified by the experiment. On the analysis, the minimum detectable pressure of the fiber-optic hydrophone was reduced by using the longer, lower loss optical fiber. Through the experiment, we have found that the detection of the accoustic field was possible by using the fiber-optic hydrophone. And the experimental results are in good agreement with the theoretical results, so it has been shown that the fiber-optic hydrophone is possible to be realized.
