In view of this, the utility model proposes a kind of bright detection means in imaging optic element periphery, it is intended to realizes center
With the accurate setting of periphery light, and by the adjusted design of optical axis and panel, realize the bright ratio in periphery detection it is steady
Qualitative and accuracy.
The technical solution adopted in the utility model is specially：
A kind of bright detection means in imaging optic element periphery, including individually adjustment unit, light are whole for luminescence unit, light
Body adjustment unit, image acquisition unit and image-display units, the luminescence unit include multiple illuminators, and these illuminators are pressed
Circular arrangement, wherein circle centre position arrange an illuminator, and remaining illuminator is circumferentially evenly arranged, and individually regulation is single for the light
Member is used for the brightness that each illuminator is individually adjusted between multiple brightness gears, and the bright integrally-regulated unit is used for many
The brightness of synchronous integrally-regulated luminescence unit between individual brightness gear, the measured optical unit is arranged on described image acquiring unit
On, the optical axis of image acquisition unit is aligned with luminescence unit center illuminator, and described image acquiring unit passes through data wire and institute
State display unit connection.
Wherein described illuminator is LED illuminator.
Wherein described image acquiring unit is video camera.
Wherein described image display unit is computer monitor.
The wherein described illuminator being circumferentially evenly arranged is at least four.
Brief description of the drawings

Week is evenly arranged, and at least four LED illuminators is arranged on circumference, individually adjustment unit 1 is used in multiple brightness shelves the light
The brightness of each LED illuminator is individually adjusted between position, so that when defect occurs in a certain position of optical element by individually adjusting
The brightness of some illuminator is saved to determine the order of severity of the defect；The bright integrally-regulated unit is used in multiple brightness shelves
The brightness of synchronous integrally-regulated luminescence unit 2 between position, in order to determine periphery of the optical element under the illumination of different brightness
Light ratio；The measured optical unit is arranged in described image acquiring unit, and the image acquisition unit is to take the photograph in this embodiment
Camera 5, the optical axis of video camera 5 is aligned with luminescence unit center illuminator, described image acquiring unit by data wire with it is described
Display unit 6 is connected, in order to which the image obtained on image acquisition unit is shown on the display unit 6.In figure
Image as shown on display unit 6 is analyzed by known image quality analysis software, so as to obtain by photometry member
Part periphery light ratio, draws the measured optical unit quality conclusion how.In this embodiment, described image display unit 6
For computer monitor.
The utility model can be embodied in other specific forms, but without departing from protection model of the present utility model
Enclose, protection domain of the present utility model is defined only by the following claims.
