Paper Abstract
Optical imaging in biomedicine is governed by the light absorption and scattering interaction on microscopic and
macroscopic constituents in the medium. Therefore, light scattering characteristics of human tissue correlate with the
stage of some diseases. In the near infrared range the scattering event with the coefficient approximately two orders of
magnitude greater than absorption plays a dominant role. When measuring the optical parameters variations were
discovered that correlate with the rheumatoid arthritis of a small joint. The potential of an experimental setup for
transillumination the finger joint with a laser diode and the pattern of the stray light detection are demonstrated. The
scattering caused by skin contains no useful information and it can be removed by a deconvolution technique to enhance
the diagnostic value of this non-invasive optical method. Monte Carlo simulations ensure both the construction of the
corresponding point spread function and both the theoretical verification of the stray light picture in rather complex
geometry.
