However, the visible window 45 is only provided on one of the faces of the housing 4, and the visible window 45 is required to be passed by the light beam emitted by the light source generating component 1, the light-free image information collected by the image collecting component 2, and the scattered light received by the image generating component 3. In addition, the positions of the light source window, the first image acquisition window and the second image acquisition window are not limited in this embodiment, the light source window may be located between the first image acquisition window and the second image acquisition window, the first image acquisition window may be located between the light source window and the second image acquisition window, or the second image acquisition window may be located between the light source window and the first image acquisition window.
