Sized-fiber array spectroscopy describes a device for measuring the absorption and reduced scattering properties of tissue. The device consists of two fibers with different diameters that measure the amount of light back-scattered into each fiber. Only one fiber emits and collects light at a time. Recent innovations allow for spatially limited measurement diffuse reflectance over a wavelength range of 500-800 nm. Reflection spectra of in vitro an din vivo porcine tissue are presented for a device with 200 and 600 micrometers fibers to demonstrate its performance.
