The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of radiation photograph detector light path system device, comprise light source, scintillation screen or the frosted glass, catoptron, the camera that are placed on the support, described light source is arranged at the upper end of described scintillation screen or frosted glass, described catoptron is arranged at the lower end of described scintillation screen or frosted glass, and being miter angle with described scintillation screen or frosted glass, described camera is arranged at the opposite end of described mirror mirror.
The further optimization of described radiation photograph detector light path system device is: also comprise lamp box cover, described light source is positioned at the inside of described lamp box cover, the described scintillation screen of uncovered butt joint or the frosted glass of described lamp box cover.
The further optimization of described radiation photograph detector light path system device is: also comprise the light transfer trunk, the described scintillation screen of uncovered butt joint or the frosted glass of described light transfer trunk, described catoptron is arranged on the interior diagonal line of described light transfer trunk, on the case face of described light transfer trunk with respect to described camera light hole is set.
The further optimization of described radiation photograph detector light path system device is: also comprise the camera camera bellows, described camera is positioned at described camera camera bellows inside, the described light transfer trunk of the uncovered butt joint of described camera camera bellows.
The further optimization of described radiation photograph detector light path system device is: also comprise the adjustment support, described camera is positioned on the described adjustment support, and described adjustment is propped up and is placed on described camera camera bellows inside.
The further optimization of described radiation photograph detector light path system device is: described light source is made as daylight lamp.
The beneficial effects of the utility model are: because the utility model radiation photograph detector light path system device uses ordinary light source to substitute X ray, and the test adjustment of radiation photograph detector light path system is reduced to position adjustment to camera, the test of radiation photograph detector light path system is separated on the proving installation carries out, therefore avoided the injury of X ray to personnel and equipment, improved the testing efficiency of radiation photograph detector light path system greatly, the utility model radiation photograph detector light path system device can also be as the testing tool of scintillation screen quality quality, this has saved cost equally, has improved detection efficiency.
