Description
Technical Field
The utility model relates to a check out test set technical field specifically is a camera lens ghost veiling glare check out test set.
Background
With the increasing of the resolution and the light transmission amount of the vehicle-mounted lens products, the market starts to have higher and higher requirements on lens ghost veiling glare, so that the requirements on automatic and accurate ghost veiling glare testing equipment become more and more urgent.
At present, a simple test mode of a common production line is to judge by manually shooting a point light source or test by test equipment provided by a special test equipment supplier, and although the test mode can realize data acquisition, the test mode also has the defects of insufficient stray light energy level, can not achieve an ideal use effect and has low test accuracy.
Disclosure of Invention
To the above problem, the utility model provides a camera lens ghost parasitic light test equipment can acquire high accuracy parasitic light energy level data, can improve the accuracy of parasitic light test again.
The technical scheme includes that the device comprises a lens to be tested and is characterized by further comprising a light source controller and a two-dimensional platform, wherein a high-dynamic camera and a photoelectric detector are mounted on the two-dimensional platform, the high-dynamic camera and the lens to be tested are arranged oppositely, a hemispherical cover is arranged on the outer side of the lens to be tested, a plurality of L ED collimated light sources are annularly arranged on the outer side of the hemispherical cover, the L ED collimated light sources are connected with the light source controller, the photoelectric detector is connected with an optical power meter, and the optical power meter, the high-dynamic camera, the two-dimensional platform and the light source controller are connected with a host end.
It is further characterized in that:
the two-dimensional platform adopts an electric two-dimensional platform.
The beneficial effects of the utility model are that, high dynamic camera with the camera lens that awaits measuring sets up relatively, and high dynamic camera accessible two-dimensional platform adjusts in order to aim at the camera lens that awaits measuring, then when shooting strong light spot through high dynamic camera and acquire the veiling glare, and photoelectric detector can mark the ghost position energy that high dynamic camera was shot to the realization acquires high accuracy veiling glare energy level data, can improve the accuracy of veiling glare test again.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a graph of the stray light level data of the present invention.
Detailed Description
As fig. 1, fig. 2 shows, the utility model discloses a lens 1 that awaits measuring, it still includes light source controller 2, two-dimensional platform 3, the electronic two-dimensional platform that two-dimensional platform 3 adopted, two-dimensional platform 3 is equipped with high dynamic camera 4, photoelectric detector 5, high dynamic camera 4, photoelectric detector 5 can remove on two-dimensional platform 3, high dynamic camera 4 sets up with lens 1 that awaits measuring relatively, the lens 1 outside that awaits measuring is equipped with hemisphere cover 6, hemisphere cover 6 outside hoop is provided with a plurality of L ED collimated light source 7, can realize the ghost expression condition of a plurality of visual angle pointolite on image surface in object space, L ED collimated light source 7 all is connected in light source controller 2, can realize controlling different angle light incidence, through light source controller 2, open one by one in proper order, cooperate high dynamic camera 4 to grab the picture, photoelectric detector 5 is connected with light power meter 8, high dynamic camera 4, two-dimensional platform 3, light source controller 2 all connects in.
The utility model discloses in, earlier through adjusting L ED collimated light source 7 light intensity, mark high dynamic camera 4 overexposure illumination level, L ED collimated light source 7 through light source controller 2 with central point on the hemisphere cover 6 opens in proper order, if central point L ED collimated light source 7, 5 position L ED collimated light source 7, 10 position L ED collimated light source 7 etc., aim at high dynamic camera 4 at the camera lens 1 that awaits measuring, and let high dynamic camera 4 can shoot the image picture of each angle light source through light source controller 2 adjustment L ED collimated light source 7 luminance, like the image of energy level 1E-7 in the miscellaneous light level graph in figure 2, change photoelectric detector 5 again and scan whole horizontal area on two-dimensional platform 3, read the illumination level data in the high dynamic camera 4 overexposure image grey level unanimity region, confirm to judge the threshold value scope of ghost, it marks to shoot ghost position energy to high dynamic camera 4 with photoelectric detector 5 data, thereby realize that the camera lens that awaits measuring ghost surpasss the ghost and judge that the ghost exceeds the ghost level.
