    • Abstract
  • A new method to improve the spatial image resolution of electro-optical sighting system is proposed. The movement of the optical double wedge was used to change the position of the imaging plane slightly. The micro-displacement sampling of the adjacent pixels and the targets in blind areas were realized without decreasing the size of the detection pixel or moving the target. The sampling rate was increased and the resolution of this system is improved using the super-resolution reconstruction technique. The experiments indicate that the method is simple and feasible, and the spatial image resolution is improved.
