Abstract :
Optical tomography of biological tissue is struggling with blurred pictures due to high scattering of photons. We describe a procedure to overcome this problem by employing measurement techniques in the frequency domain in order to determine the optical impulse response function. After introducing problems of optical tomography and realized solutions, an arrangement is described which utilizes frequency domain measurements based on direct modulation of a laser diode and detection by a photodiode. The principle function is demonstrated by measuring optical properties of a test system
