The invention provides a dual-energy-band pulse neutron image detection device and method, and solves the problem that it is difficult to obtain two-energy-band neutron images for accurate comparison, and the neutron images are transmitted to a camera through an image conversion screen, a first image coupling structure, an image intensifier and a second image coupling structure and are recorded. A space response uniformity calibration and time triggering system is additionally arranged, the space response uniformity calibration and time triggering system comprises a pulse uniform radiation source and a triggering control unit, the pulse uniform radiation source is used for calibrating the space response uniformity of the image detection system, and the image detection system provides accurate incident neutron flux space distribution; the trigger control unit can accurately trigger the camera and control the opening time and gain coefficient of the image intensifier, so as to obtain two images at a shorter tim
