| Abstract: | Measuring the temporal-spatial distribution of far-field laser beam profile is an effective way to analyze the atmospheric transmission effects of high power laser and evaluate the characteristics of laser system. Several methods for measuring the laser far-field beam profile and their respective features are summarized, and the measuring technology based on array detector is mainly described. Finally, two laser beam profile measuring systems with photo-electric detector array are developed, which are respectively applied to measuring the far-field beam profile of high energy laser and repetitively pulsed laser. These measuring systems are compact and very suitable for moving test targets. |
