Description

  The present invention relates to an aiming device that improves visibility during gun shooting.

  In the conventional sighting device, the objective part and the eyepiece part are integrated into a cylindrical shape, and it is necessary to look into the cylinder in order to visually recognize the internal aiming point.

  There are also sighting devices that can move the eyepiece, but there is a restriction on the movement (movement) of the eyepiece because it is a system that reflects the light with a mirror or the like and extends the tube in accordance with the direction of reflection.

  A scope or dot sight used as a gun sight is a cylindrical sight, and the sighting point cannot be visually recognized unless a tube (eyepiece) whose position cannot be mechanically changed is looked into. Therefore, if an enemy is found when the gun is not held (not looking into the sight), there will be a delay due to the action of looking into the sight.

  In order to solve the above-described problems, the aiming device of the present invention includes an objective unit that includes a doped fiber that receives external light from the objective side and gradually decreases in diameter from the incident end to the output end for reducing the image.

And a reception display unit including a display unit for displaying an image signal from the image processing unit.

  In the present invention, the incident light from the objective part is sent to the eyepiece part by the optically-doped relay-doped fiber, so that the relay-doped fiber can be flexibly moved, and the eyepiece part can be installed at a position and angle useful for the shooter. As a result, it is possible to improve the responsiveness at the time of shooting and to improve the visibility of the aiming position.

The amplifying unit 23 has an interface to which the relay doped fiber 151 can be connected, and amplifies the transmission light (image) from the relay doped fiber 151 on the objective unit 11 side. The output end of the amplifying unit 23 is connected to the input end of the image processing unit 24, and the image processing unit 24 sends a digital signal obtained by digitally converting the transmission light (image) amplified by the amplifying unit 23 to the input end of the radio unit 25.
