Embodiment 1
[0040] Such as figure 2 As shown, the device includes a blue light source 1, a camera composed of a lens 2, a beam splitter 3, a blue light bandpass filter 4, a blue light cut filter 5, a first image sensor 6, and a second image sensor 7. And computer 8; Illumination area 11 to be measured with blue light source 1 in the mode of backlight, dichroic prism 3 is installed on the back of first lens 2, and first lens 2 receives the light beam that blue light source 1 emits and measured particle scattering in area 11 to be measured The beam splitter 3 divides the light entering the first lens 2 into two beams with the same spectral composition and intensity. One beam is filtered by the blue light bandpass filter 4 and then received by the first image sensor 6, and the other beam is filtered by the first image sensor 6. After being filtered by the blue light cut filter 5, it is received by the second image sensor 7, and the first image sensor 6 and the second image sensor 7 convert ...
Embodiment 2
[0058] The blue light band-pass filter 4 and the blue light cut-off filter 5 among the embodiment 1 are plated on the surface of the first exit surface B and the second exit surface C of the beam splitter 3 in a film mode, as image 3 As shown, the beam splitter 3, the blue light bandpass filter 4 and the blue light cut filter 5 in the first embodiment constitute a whole, and the steps of the measurement method are the same as those in the first embodiment.
Embodiment 3
[0060] The blue light bandpass filter 4 and the blue light cut filter 5 in Embodiment 1 are screwed into the camera, that is, fixed in front of the first image sensor 6 and the second image sensor 7, as Figure 4 As shown, the measurement method steps are the same as in Example 1.
