Concept of the reflected light intensity measurement. (a) The upper fiber-optic channel emits the light which is reflected on the mirror. The lower fiber-optic channel collects a fraction of the reflected light. (b) If the mirror is placed at a larger distance, the second fiber-optic channel collects more light.
