AIMING DEVICE, ESPECIALLY FOR A HEAD-MOUNTED AIMER |
摘要 |
An image forming a sighting reticle can be displayed at infinity in the landscape under observation without any need for a collimating optical system. To this end, a birefringent crystal plate having parallel faces is placed between two crystal plates employed as polarizing filters and consisting respectively of a polarizer and an analyzer in order to produce the reticle in the form of interference fringes centered on the line of sight. The very lightweight sighting device can be integrated in one eye-glass of a spectacle frame or in a helmet visor. Complementary diodes can be incorporated in the device for providing information relating to directional prepositioning and the like. |
