| 摘 要： | 为了提高低相干干涉技术(LCI)的测量精度,满足实际中高精度测量的要求,本文对LCI中的光拍频噪声进行了详细的理论研究、推导出拍频噪声的基本公式,并通过LabVIEW对噪声的性质进行仿真分析。结果表明:拍频噪声大小与光源功率的平方成正比,信噪比随光源功率线性增加并达到饱和值。

| Abstract: | In order to improve measurement precision of LCI and satisfy the need of high precision measurement practical- ly,this paper makes a detailed theoretical study of the optical beat noise and then derive a basic formula.The nature of the beat noise is simulated and analyzed through LabVIEW.The results show that.the beat noise is directly proportional to the square of source power and signal to noise increases linearly with the power and reaches the saturation values at last. |
