As a disease of bone "Osteoporosis" is a fatal threats in elder. Testing bone densities with "Duel Energy X-ray absorptiometry (DEXA)" in present provide expensive cost and harmful. We research the probability to create the noninvasive method by using knowledge of tissue optic. The potential of Near-Infrared (NIR) spectra are used to investigate the Absorption of the phantoms. The wavelength 800 and 1750 nm were used to consider the different between thickness and concentrations of bone for study the total intensity transmittance
