Description
Technical Field
The utility model relates to the technical field of optical sighting devices, in particular to an optical sighting telescope for reducing active laser reconnaissance threats.
Background
An optical sighting telescope is an optical mechanical structure which is arranged above a firearm and helps a gunman to quickly aim and shoot. The first truly practical optical sighting telescope is born in the first battle and develops well in the second battle. By means of the optical sighting telescope, the gunman can be hidden in buildings, rooftops, jungles and even grasses, the enemy target can be killed at a long distance, and the efficiency is extremely high.
With the development of military photoelectric technology, the laser active reconnaissance anti-sniper equipment can effectively find and lock the position of a gunman. This is because the reticle used for ranging and sighting in a common military optical sighting telescope is usually located at the image-wise focal plane of the sighting telescope objective. When an enemy utilizes the laser active reconnaissance device to emit laser to the gunner direction, the objective lens converges the incident laser to the surface of the reticle. Because the surface of the dividing plate has certain reflection properties, part of incident laser energy is reflected by the dividing plate and returns along the original optical path, and a remarkable laser echo signal is formed. If the part of laser echo signals are detected by the laser active reconnaissance device of the enemy, the specific direction of the gunman of the party is exposed, and the gunman faces serious threat of laser active reconnaissance.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an optical sighting telescope capable of reducing active laser reconnaissance threats, which can automatically complete the assembly process of insulators, improve the working efficiency and reduce the error rate and labor cost.
In order to achieve the purpose, the utility model adopts the following technical scheme:
an optical sighting telescope for reducing active laser reconnaissance threat comprises a main light path channel and an imaging light path channel arranged perpendicular to the main light path channel, wherein the main light path channel comprises an eyepiece group, an image rotating group, a converging lens and an objective group which are sequentially arranged in parallel along the light path direction; the half-reflecting and half-transmitting lens is arranged between the converging lens and the objective lens group and used for deflecting the imaging light path direction by 45 degrees, so that the image surface of the inverted real image of the illuminated reticle is positioned on the main light path and is superposed with the image focal plane of the objective lens group, and the measurement and the aiming of the reticle are realized.
The imaging light path channel also comprises an LED converging lens used for illuminating the reticle, and the LED converging lens can converge light beams passing through the objective lens group to a certain degree, so that the aperture of the image rotating lens group is reduced.
The image rotating lens group is used for turning the inverted real image of the reticle and the inverted real image of the target into upright real images, and observing the images through the eyepiece group.
According to the technical scheme, the optical sighting telescope for reducing the active laser reconnaissance threat replaces a solid reticle with a reflection property by using a real image formed by the reticle through the imaging lens group and the spectroscope. When the laser active reconnaissance system of the enemy emits laser beams to the direction of the sighting telescope, the sighting telescope does not reflect the reconnaissance laser, so that the reticle system provided by the utility model ensures that no entity reticle which can have reflection attribute exists in the optical path of the optical sighting telescope, eliminates laser echo generated in the process of implementing laser active reconnaissance by the enemy, is not easy to expose the direction of a gunman of the enemy, reduces the threat of laser active reconnaissance, and can protect personal safety.
