用列阵相机测1.06μm波长激光束远场角分布,采用黑白胶片感光,列阵点不易读准,且受显影条件的影响,而采用紫外示波纸就可避免这些缺点,两者测量光束角分布的结果吻合。用紫外示波纸测量光束70%能量的光束发散角相对误差起伏最大为10%,而光束70%能量的平均发散角处的能量相对起伏在5%以内
Using an array camera to measure the far-field angle distribution of a laser beam with a wavelength of 1.06 μm, black-and-white film is used for sensing, and the array point is not easy to read and read and affected by the developing conditions. However, both of these disadvantages can be avoided by using ultraviolet oscillographic paper Beam angle distribution of the results match. The relative error fluctuation of the beam divergence angle of 70% of the energy of the beam measured by the ultraviolet oscillographic paper is 10% at maximum, and the energy at the average divergence angle of 70% of the beam energy is within 5%
