For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Aforementioned known, namely the scopic principle of laser precipitation phenomenon, when precipitation particles is by test zone, understands the laser beam blocked on certain hour and spatial dimension in test zone, affect the intensity distributions of laser beam, and then produce the change of light sensation electric current on the optical sensor; And namely laser precipitation phenomenon scopic output data can be calculated by the change of described light sensation electric current.The scopic reckoning process of laser precipitation phenomenon is prior art, and therefore not to repeat here.
Be understandable that based on this principle, to be tested laser precipitation phenomenon visualizer by simulated precipitation particle, be exactly some the shading particle needing to utilize similar precipitation particles shape, size and area in essence, speed during to decline close to precipitation particles passes through test zone.Reach the effect of simulated precipitation particle thus.
In the utility model embodiment, the scopic proving installation of a kind of laser precipitation phenomenon will be disclosed.Described device, by the transparent former dish of a controllable rotating speed, posts simulation paster, and described simulation paster just plays the effect of so-called shading ion; Described transparent former dish is placed in the scopic test zone of laser precipitation phenomenon rotate, makes described simulation paster reach certain linear velocity, play the effect of simulated precipitation particle thus.
