侧向偏移成像技术是一种新的康普顿背散射X射线成像技术，被应用于地下地雷的探测和识别。研制了一种移动的激光磁共振地雷探测系统，并进行了实地测试。该初始系统的重量约为175 kg;原型的重量应约为100 kg。X射线发生器的功率水平为750瓦;原型的功率水平要求应为300瓦左右。开发了一种用于X射线源光束的创新旋转准直器，以提供光束的快速侧到侧扫描，而无需在该方向上移动X射线发生器。根据所需的分辨率，采集40 cm × 40 cm区域的图像需要30至60秒。LMR的成像能力使其非常适合用作地雷探测确认传感器。该系统于2001年10月在Fort A. P. Hill的车辆测试车道上使用。获得了各种埋藏地雷的高质量图像。该系统还用于扫描其中一条测试车道上的30个位置，在这些位置，GPR始终产生错误警报。只有在两个案例中，激光磁共振图像集产生的特征可被认为可能表明有地雷。
Lateral migration radiography (LMR), a new form of Compton backscatter x-ray imaging, is applied to the detection and identification of buried land mines. A mobile LMR land mine detection system was developed and field tested. Weight for this initial system was about 175 kg; weight for a prototype should be about 100 kg. X-ray generator power level was 750 watts; the power level requirement for a prototype should be about 300 watts. An innovative rotating collimator for the x-ray source beam was developed to provide rapid side-to-side scanning of the beam without having to move the x-ray generator in this direction. Acquisition of images of a 40 cm by 40 cm area takes from 30 to 60 seconds, depending on the desired resolution. The imaging capabilities of LMR make it well suited for use as a land mine detection confirmation sensor. This system was employed on the vehicular test lanes at Fort A.P. Hill in October, 2001. High quality images were obtained for a variety of buried land mines. The system was also used to scan 30 locations on one of the test lanes where GPR consistently yielded false alarms. In only two cases did the LMR image sets yield a signature that could be considered to possibly indicate a mine.
