| 摘 要： | 针对不可避免的激光光束的指向误差带来的干涉条纹抖动,去除干涉图像高频部分从而找到干涉条纹抖动量并进行误差消除.在非局域空间光孤子大相移的测量实验中,运用此方法,成功地得到了消除激光器指向误差的相位随功率的变化图,从而实现了非局域空间光孤子大相移的测量.

| Abstract: | To delete the measuring error of the optical phase shift resulting from the dithering of the interference fringes,a method is introduced.This method aims at the beam pointing instability induced fringe shift.The high frequency parts of the interference figures are get rid of,accordingly the quantity of the interference fringes dithering can be obtained.Based on this method,the phase shift of the soliton changing with the soliton power is obtained without the laser pointing instability error and the phase sh... |
