Optical Properties Assessment for Liquid Phantoms Using Fiber Based Frequency-Modulated Light Scattering Interferometry

På svenska

Author

Summary, in English

Fiber based frequency-modulated light scattering interferometry (FMLSI) is developed for optical properties studies of liquid phantoms, made of Intralipid (R). By employing optical frequency modulation on a tunable diode laser, the power spectrum of the heterodyne-detected intensity fluctuations through the dynamic turbid medium is a combination of the time-of-flight distribution and the Doppler power spectrum due to the movement of the scattering particles. The reduced scattering coefficient, absorption coefficient and Brownian diffusion constant are retrieved by employing nonlinear fitting to the power spectrum based on diffusion theory.
