Lately, I am trying to solved the data that I got from the Monte Carlo (MC) Simulation for photon propagation in turbid media using the diffuse reflectance approximation equation (used in the program). However, when I used, An error occur : new int. coeff. is needed.

Am I doing something ??

The optical properties used in the MC program is mu_s prime = 10 , mu_a = 0.1 , and r = 1

In the program -> (a) (b) ©

Thanks

The program is working. I used you example, just changed the formula and it worked. Thanks very much

I'll explain why I want to fit the diffuse appox. equation:

The program fit for the diffuse reflectance, R(r,t), for the sample.

The device:

We are using two fiber optics, one as emitter and the other as collector.

Results:

By fitting the curve, you can obtain optical properties of sample ( absorption coeff., scatter coeff prime and the distance between the fiber optics).

Thank you for your help.

I am a beginner in LV and My problem is something like this.

I am trying to fit the photon diffuse equation. I am testing the command before using really data. Therefore, I generate the equation waveform then use the nonlinear fitting to solve it. however, the fitting is not right.

Also I am having problem in graphing the fitting curve.

Thanks.
