| 摘 要： | 根据激光发散角经准直后的微小角度的测量理论,提出了采用远场焦斑和CCD进行快速准确的测量方法,最后实际测出了激光准直后的远场发散角。实验证明:采用该方法可以达到空间光通信的激光发散小角度微弧度量级的要求,并且所带来的误差小于国际标准组织规定的最大值。

| Abstract: | The key technique in optical communications is the narrow beam orientation. According to the small-angle measurement theory of laser alignment system divergence, an accuracy and high-speed measuring method using Charged Couple Device (CCD) is proposed to measure far-filed focus facula. The far-field divergence of laser alignment systems is measured experimentally. The results demonstrate that the error produced by this method is less than the maximum of International Standardization Organization. |
