基于混沌激光互相关峰值实现脂肪乳液内异质物的检测
|
摘要
利用混沌激光互相关峰值实验实现了脂肪乳液内部异质物的检测。在脂肪乳液内放置异质物,以自相关函数具有delta函数特征的混沌激光作为光源,将混沌激光分成两路,一路入射到带有异质物的脂肪乳液内,通过脂肪乳液后经光电探测器接收、输出后作为探测信号;另一路经光电探测器输出,作为参考信号。将混沌激光参考信号与经过脂肪乳液的混沌激光进行互相关,混沌激光的互相关峰值反映了脂肪乳液及其内部异质物的光学信息。结果表明,混沌激光相关检测法具有很强的抗干扰性。
Herein, foreign object detection in the intralipid solution has realized by the cross-correlation peak of chaotic laser. The foreign objects are put inside the intralipid solution. Chaotic laser with delta characteristics of autocorrelation function is used as the detection source and divided into two parts. The first part is used to illuminate the intralipid solution, wherein the detection signal is received and output by the photoelectric detector through the intralipid solution. The second part passes through the photoelectric detector as the reference signal. The reference signal is cross-correlated with the chaotic laser passing through the intralipid solution. The optical informations of the intralipid solution and its internal foreign objects are reflected by the cross-correlation peak of the chaotic laser. Results show that the correlation detection method of chaotic laser has a strong anti-interference.
