Auto-switch device for non-uniformity correction of infrared camera

More Information
  • Infrared camera used for capturing and tracking target mainly was one of the most important equipment in laser weapon system, and its non-uniformity disturb influenced infrared target extraction greatly. To decrease noise disturb and improve imaging quality, a switch machine was designed to correct nonuniformity of infrared camera when it was started up. Considering confined applying conditions, a crank-link switching device was designed particularly on the basis of contrasting and analyzing auto-switch devices with different structure principle. The designed switch device was driven by tubular solenoid and drive was transferred by crank-link. Applying effect shows the sizes of designed switch machine is 68 mm36 mm37 mm and the switch time is about 0.4 s, so it is more suitable in the occasion of small space .
