摘要

通过将透射辐射聚焦到吸收介质中，对不透明物体的反像形成进行了数值模拟。结果表明，这一过程在很大程度上取决于物体尺寸与照射光束的比例。相对于光束的初始强度，小尺度物体的逆图像转换超过350%。

Numerical simulation of contrast inversion process when focusing laser beam in the absorbing medium

A numerical simulation of the inverse image formation of opaque objects by focusing the transmitted radiation into the absorbing medium is performed. It is shown that the process strongly depends on the ratio of the size of the object and the illuminating beam. Inverse image conversion exceeds 350% for small-scale objects, relative to the initial intensity of the beam.
