Description
Technical field
The utility model relates to the dynamic black matrix calibration source of a kind of external.
Background technology
Along with the development of modern infrared electro technology, the application of infra-red thermal imaging system in military-civil field is increasingly extensive.The core component of thermal imaging system is infrared focal plane detector (IRFPA), and due to the limitation of infrared focal plane detector manufacturing process, the responsiveness of each probe unit has inconsistency, also referred to as fixed pattern noise (FPN).When variation of ambient temperature when IRFPA works long hours or work is larger, FPN can produce new drift change, reduces temperature resolution and the visuality of infra-red thermal imaging system, becomes the principal element of restriction infrared focal plane device application.In order to ensure the temperature resolution of thermal imager system under complicated environmental condition and image quality, the Nonuniformity Correction (NUC) of IRFPA becomes the hot spot technology that Now Domestic is studied outward.
The asymmetric correction method of thermal infrared imager comparatively ripe at present has two kinds: 1. use standard blackbody before product export, carry out static shift correction to thermal imaging system.2. fast door guard plate is used to carry out single point correction after product export.These two kinds of NUC calibrating modes are applicable to the application scenarios that temperature variation is less, stream time is shorter.
