NONLINEAR-OPTICAL PROCESSING BY MEANS OF phase coding
收藏 引用
OPTICS LETTERS 1991年 第18期16卷 1418-1420页
作者: SADOVNIK, L SAWCHUK, AA CHEN, R JANNSON, T UNIV SO CALIF INST SIGNAL & IMAGE PROCLOS ANGELESCA 90089
A new look at nonlinear-optical processing that uses Fourier plane filtering is discussed. Traditional binary intensity-to-space recording (halftoning) is replaced by simple continuous phase coding. Some proof-of-prin... 详细信息

COGNITIVE NEURODYNAMICS 2007年 第2期1卷 169-184页
作者: Igarashi, Jun Hayashi, Hatsuo Tateno, Katsumi Kyushu Inst Technol Dept Brain Sci & Engn Grad Sch Life Sci & Syst Engn Kitakyushu Fukuoka 8080196 Japan
We investigated successive firing of the stellate cells within a theta cycle, which replicates the phase coding of place information, using a network model of the entorhinal cortex layer II with loop connections. Laye... 详细信息
