Embodiment 1
[0046] Such as figure 1 As shown, the high-pressure combustion carbon black particle concentration measuring device of the present invention includes a laser 1, a first attenuator 3, a beam expander collimating mirror 4, a first polarizer 7, a high-pressure sample chamber 8, a second polarizer 9, and a focusing lens 10. A first optical filter 11 , a linear array CCD image sensor 13 and a computer 19 . For the convenience of description, the exit end of the laser light emitted by the laser 1 is defined as the front. The present invention will be further described below by taking the measurement of the concentration of burning carbon black particles as an example.
[0047] The laser 1 is the light source of the device for measuring the concentration of high-pressure combustion carbon black particles of the present invention. The laser 1 in this embodiment adopts a tunable laser that can emit laser light of different wavelengths. Behind the laser 1 in the direction of the horiz...
