B) It provides a distorted view of the scene to the user situated at 90° to the side of the host device, for example for enhancing the FOV of the scene.
  • the attached panoramic sight system may be used by the user positioned behind the host device and viewing the scene and the host aim through the second image combiner path. Accordingly the user may aim/ shoot the host device without the need to detach the panoramic sight system from the host device.
  • the panoramic sight system may comprise an adjustable shutter which at its closed position may substantially block the light penetration and thus increase the contrast to the scene when viewed by the user at 90° to the host device.
