    Ultrafast imaging is an important method for studying ultrafast phenomena such as explosions and high-voltage discharges. All-optical framing imaging has great development prospects because it can overcome the time limitation of optical-to-electric signal conversion. In this study, an all-optical spatial framing imaging system is constructed using a diffractive optical element and a band pass filter, the array framing imaging is successfully realized, and the results of different bands are analyzed. The experimental results show that the designed all-optical spatial framing imaging system can realize 16-framing imaging in a 4×4 array in different wavelength bands. The relative standard deviation of the non-uniformity between the image frames is 7.4%, and the average deviation of the non-uniformity within a frame is 2.83%. Further, the modulation transfer function of the all-optical framing imaging system is 0.991 at resolution of 35 lp/mm.
