Optimal Feedback Control of Two-Photon Fluorescence Based on Genetic Algorithm

An optimal feedback control of two-photon fluorescence in the ethanol solution of 4-dicyanomethylene-2-methyl- 6-p-dimethyl-aminostryryl-4H-pyran （DCM） using pulse-shaping technique based on genetic algorithm is demon- strated experimentally. The two-photon fluorescence of the DCM ethanol solution is enhanced in intensity of about 23%. The second harmonic generation frequency-resolved optical gating （SHG-FROG） trace indicates that the effective population transfer arises from the positively chirped pulse. The experimental results appear the potential applications of coherent control to the complicated molecular system.     

一种红外成像制导中的图像分割算法

红外成像制导导弹的图像分割是图像处理中的重点和难点之一。针对飞机目标红外图像的特点,提出了一种有利于目标特征点识别的图像分割算法。它首先采用区域填充的方法对图像进行分割,然后在此基础之上利用形态学原理对分割过程中产生的"洞"区域进行填充,最后得到比较精确的分割图像。对于实现红外成像制导导弹的稳定跟踪具有一定的应用价值。
