Abstract

The utility model discloses a semiconductor laser range finding gun applied sighting telescope. The telescope adopts a semiconductor laser range finding technology with a 905nm wavelength by allowing prism groups to split optical paths with the result that a laser reflecting optical path, a laser receiving optical path and a sighting optical path share one object lens. A common focal plane is formed on the surface of a prism group and on the surface of the focal plane is placed a pen drawing type crystal display screen with which a user could find the range of an aiming point and find out distance parameters of a target or could calculate the values of a marked ruler based on the information on the distance, the surrounding temperature and the pressure; the common focal plane is also placed with an optical marker which is provided for a shooter to aim to the marked ruler. The optical marker can also move in parallel and perpendicular to an optical shaft to make remedies to the gun shaft.

Description

The semiconductor laser range riflescope

Affiliated technical field

The invention belongs to a kind of semiconductor laser range riflescope that is used for the firearms aiming.

Background technology

At present; General mechanical scale or the ordinary optical gun sight of adopting of the shooting aiming of firearms; Shortcoming is can not be in time accurately to measure target range, and the factor that influences fire accuracy such as environment temperature and air pressure is reflected in that set on the scale amount can only the summary estimation, thereby influences fire accuracy.In recent years along with the progress of equipment technology; The laser ranging gun sight that the ability precision ranging occurred; Can information such as the target range that records, environment temperature and air pressure be calculated the scale amount that sets through microprocessor; The dress mark information projection that LED, OLED or nixie display is shown through prism system is taken aim to sight and is realized in the optical system adorning the mark function automatically, has improved fire accuracy.The laser ranging gun sight shortcoming of this kind is: the prism system complex structure, be difficult for debugging, and cause laser ranging gun sight volume big simultaneously, Heavy Weight is installed on the firearms inharmoniously, and influence is used.

Summary of the invention

Content of the present invention provides a kind of semiconductor laser range riflescope that is applicable to the firearms aiming.

The technical solution that realizes content of the present invention is: adopt the semiconductor laser range technology of wavelength 905nm, through prism component light light path, make Laser emission light path, laser pick-off light path and sight take aim at the shared object lens of light path.After focal plane of lens, form a conjugate focal planes through a set of lenses; Focal plane of lens fixed placement stroke system LCD shows range finding aiming point, target range value or the scale amount that sets that calculates through information such as target range, environment temperature and air pressure.Conjugate focal planes is placed the optics graduation, provides leaf sight to supply shooter's aiming.The optics graduation can be moved perpendicular to the aiming optical axis is parallel, is used for and the calibration of rifle axle.

The present invention compared with prior art, its beneficial effect is: 1) simple in structure, reliability is high, and cost is low; 2) volume is little, and is in light weight, is applicable to firearms.

The specific embodiment

Fig. 1 has explained semiconductor laser range riflescope system works principle, and operation principle is following:

Sight is taken aim at part and is made up of object lens [1], prism group [2], stroke system LCD [3], set of lenses [4], optics graduation [5] and eyepiece [6] parts.Target supplies shooter to observe and aiming through seeing to take aim at after part is amplified.Stroke system LCD [3] fixed placement overlaps with target imaging at the focal plane of lens place.Stroke system LCD [3] receives computer and Programmable Logic Controller [13] control by power circuit [11] power supply, shows range finding aiming point, target range value or the scale amount that sets that calculates through information such as target range, environment temperature and air pressure.Set of lenses [4] forms a conjugate focal planes after focal plane of lens, optics graduation [5] overlaps with conjugate focal planes, i.e. optics graduation [5] overlaps with target imaging.Leaf sight is carved with in optics graduation [5], supplies shooter's aiming.Optics graduation [5] can be moved perpendicular to the aiming optical axis is parallel, is used for and the calibration of rifle axle.

Laser ranging partly is made up of power circuit [11], radiating circuit [17], laser instrument [16], emission light path [15], receiving light path [7], receiver [8], signal processing circuit [9], computer and Programmable Logic Controller [13], object lens [1] and prism group [2] parts.After pressing range finding button [14]; Computer and Programmable Logic Controller [13] control power circuit [11] is given each functional part power supply; Radiating circuit [17] triggers the laser that laser instrument [16] produces wavelength 905nm; Laser behind the raising beam quality, shines target through prism group [2] and object lens [1] through the shaping of emission light path [15].Return laser beam after the target diffuse reflection converges on the photosurface of receiver [8] through receiving light path [7] through object lens [1] and prism group [2], and receiver [8] produces the signal of telecommunication, is handled by signal processing circuit [9].In the time interval through Laser Measurement emission and echo arrive, calculate target range.
