For the measurements of temporal and spatial distribution parameters of high energy laser beams, a synthetic measurement of calorimetric and photoelectric method is studied. The data fuse of two kinds of sensors is achieved with a real-time scaling technique. Then, a set of compound measurement system is developed for measuring the large caliber laser beams. The system is mainly composed of 256 calorimetric detectors, 120 photoelectric detectors, multi-channel data sampling modules and one central processing computer. The total energy of the laser beam is precisely measured with the calorimetric detectors, and the high temporal and spatial resolution distribution is given with the photoelectric detectors. With the merits of accurate energy and the high temporal resolution of two kinds of sensors, the compound system can be used for absolute measurement of the far-field temporal and spatial distribution of high energy laser beams.
