The invention belongs to the technical field of photoelectric detection, and particularly discloses a device and a method for measuring laser intensity distribution. The device comprises a conical sampling hole, an integrating sphere, a photoelectric detector and a light outlet hole, the surface of the conical sampling hole is of a mirror reflection structure, and the inner wall of a sphere cavity of the integrating sphere is of a diffuse reflection structure; the conical sampling hole and the light emitting hole are both formed in the integrating sphere, and the central axis of the conical sampling hole does not coincide with the central axis of the light emitting hole; and the photoelectric detector is arranged outside the light outlet hole and is used for receiving emergent light. The invention has a good incident angle tolerance characteristic. 本发明属于光电探测的技术领域，具体公开了一种用于激光强度分布测量的装置及方法。所述装置包括锥型取样孔、积分球、光电探测器和出光孔；所述锥型取样孔的表面为镜面反射结构，所述积分球的球腔内壁为漫反射结构；所述锥型取样孔和所述出光孔均设置在所述积分球上，并且所述锥型取样孔的中轴线和所述出光孔的中轴线不重合；所述光电探测器设置在所述
