Step light application in optical tomography

In this paper we propose a method of characteristic value extraction for image reconstruction by using step light probe biological tissue. First of all, the method shows that we can recover the spatial distribution of the optical parameters. What is more, this theory can be applied to solve the problems that are similar with optical imaging. No matter what form of incentives, we can calculate their response using the forward model, and find the physical means to measure the response. We can use this theory to solve it. This article is a verification of the application of optical imaging to the problems above.
