In this Letter we present a simple and novel theoretical approach for modeling the intensity distribution from an arbitrarily shaped turbid volume in a noncontact geometry by considering diffuse light propagation in free space. This theory is validated with experiments for a diffusive volume of known geometry in a noncontact situation, both with and without the presence of an embedded absorber. The implications of this new formulation in the context of optical tomography in turbid media are discussed.
在本信函中，我们提出了一种简单且新颖的理论方法，通过考虑自由空间中的漫射光传播，对非接触几何形状中任意形状浑浊体的强度分布进行建模。该理论在非接触情况下，针对已知几何形状的扩散体进行了实验验证，实验中既有嵌入吸收体的情况，也有未嵌入吸收体的情况。讨论了这种新公式在浑浊介质光学层析成像背景下的意义。
