摘要：
The measurement system 110 comprises a light source 120 configured and arranged for emitting a light beam via a polarization modulator 130 to a target position inside the skin 160 wherein the polarization modulator 130 is configured and arranged to simultaneously provide in use a first and a second region in a cross section of the light beam in the target position the first and the second region being distinct and having a corresponding first and second direction of polarization the first and the second polarization direction being different from each other and the measurement system also comprises a detection unit 150 to simultaneously detect a first and a second intensity of reflected light 145 the first intensity corresponding to light reflected from the first region of the light beam in the target position 160 and the second intensity corresponding to light reflected from the second region of the light beam in the target position 160 and the measurement system further comprises a processor being coupled to the detection unit 150 for determining a difference between the first and the second intensity.
