摘要：本文提出了一种新的测量超连续谱激光器光束发散角和光束轮廓均匀度的新方法——高光谱成像（HSI）。所获得的发散角结果与理论计算值一致。通过参考HSI 相机提供的数据集，测量了不同尺寸投影高斯光束在波长变化下的均匀度。与传统方法相比，HSI 速度更快，能够为超连续谱输出参数测量和远场情况下的实际应用提供关键参考。

Hyperspectral imaging for the spectral measurement of far-field beam divergence angle and beam uniformity of a supercontinuum laser
Abstract: A new novel method, hyperspectral imaging (HSI), is presented in this work to measure the beam divergence angle and beam profile uniformity of supercontinuum lasers. The obtained results of divergence angles are consistent with theoretically calculated values. The uniformity of different-size projected Gaussian beams was measured through referencing the data sets provided by HSI camera under the wavelength variation. HSI, compared with traditional methods, is much faster and capable of providing critical reference to supercontinuum output parameters measurements and practical application in far-field situation.
