The application relates to a method and device for imaging an object through photoneutron transmission. The method uses photoneutron rays to transmit the object, and comprises the following steps: emitting photoneutron rays by a photoneutron source to irradiate on the object; receiving the photoneutron rays from the photoneutron source by a detector; and imaging the object based on the photoneutron rays received by the detector; wherein the detector can slow down and absorb the photoneutrons, and wherein the incidence direction of the photoneutron rays from the photoneutron source and the normal direction of the detector surface form an angle ranging from 60 degrees to 87 degrees, or from about 60 degrees to about 87 degrees. |
