本文在严格的远区散射场的框架下,探讨了物象重建问题。指出在散射一逆散射问题中,只存在两维傳氏对偶空间。文中提出在单一波数,单一入射并且小成象角条件下成象的似视原理。揭示了在散射成象问题中存在着成象角与工作波长的互补关系。理论结果由计算机模拟得到验证。最后对用波的理论解释人的视觉机制作了尝试。
In this paper, under the framework of strict far-field scattering field, the problem of object reconstruction is discussed. It is pointed out that in the scattering-inverse scattering problem, there is only two-dimensional Legendwell dual space. In this paper, we propose a similar visual principle of imaging at a single wave number, a single incidence and a small imaging angle. It is revealed that there is a complementary relationship between imaging angle and working wavelength in the problem of scattering imaging. The theoretical result is verified by computer simulation. At last, we try to explain human visual mechanism by the theory of wave.
