    摘要： A method for imaging an object by means of photoneutron transmission is provided, which comprises the steps of: collimating the photoneutron rays passing through the object by means of a neutron collimator so as to determine the position information of the photoneutron rays based on the position of the neutron collimator; detecting the collimated photoneutron ray beams by means of a detector module, wherein the detector module includes a neutron moderator and at least one thermal neutron detector located within the neutron moderator, wherein the neutron moderator converts the photoneutrons into thermal neutrons, and wherein the thermal neutron detector measures the thermal neutrons so as to obtain attenuation information of the photoneutron ray beams upon passing through the object; and integrating the position information and the attenuation information so as to form an image of the corresponding part of the object. The method determines the position of the photoneutron rays based on the position of a neutron collimator, so as to overcome the problem of incapability of imaging due to loss of position information of the photoneutrons during moderation thereof. The method also images the object by arranging detector module arrays.
