:: Scott Prahl's web page. This is probably the most useful resource in the web for those of us using light to study biological tissues. It has very useful spectra. A must-visit web page if you work in bio-optics.
:: Steve Jacques and Lihong Wang's web page. From older work of them, they have very useful monte-carlo codes. I strongly recommend you visit them if you intend to use Monte Carlo to study light propagation.
:: Medphot web page. A good resource for optical properties of tissue.
:: David Boas' group web page. Several programs that are very useful.
:: TOAST web page. The web page of Simon Arridge's work, one of the pioneers in Optical tomography. TOAST is a software (now also available for matlab) that uses finite elements (FEM) to solve the diffusion equation for any boundary and perform the inversion.
