近年来,编码孔径三维成象技术在射电天文、雷达、X射线成象、γ射线成象及核子成象等领域获得迅速发展.由于它是在那些至今尚未获得有效相干源的波段中实现全息记录的主要手段,因此在层析诊断、无损探伤、核反应堆监测等技术领域有着广泛的应用前景.计算机断层扫描(CT)技术的高 In recent years, coded aperture three-dimensional imaging technology has been rapidly developed in the fields of radio astronomy, radar, X-ray imaging, gamma ray imaging and nuclear imaging, etc. Since it is the hologram in the wavelength band that has not yet obtained an effective coherent source Therefore, it has a wide range of application prospects in the fields of tomography, non-destructive testing, nuclear reactor monitoring, etc. The high level of computed tomography (CT)
