Description
Technical field
The present invention relates to the aiming utensil of weapon, refer in particular to a kind of technology that sets of holographic aiming device distance scale.
Background technology
Existing holographic aiming device principle as depicted in figs. 1 and 2, utilize a high-quality laser diode 0 or 7 to send beam of laser, be an oblique grating planar 3 or 10 of being mapped to of parallel beam through optical system 1 or 9 collimations, 1 order diffraction light by the grating outgoing still is collimated laser beam, this laser beam incides on the holographic facet 5 or 11 that is loaded with the graduation pattern again, and human eye can be seen the graduation pattern by-1 order diffraction light beam of holographic facet outgoing.Here, the effect of grating mainly is in order to compensate the pointing error that the optical maser wavelength drift produces.Because along with variation of temperature, the light beam wavelength that semiconductor laser sends can produce drift in a small amount, if the laser beam direct irradiation holographic facet behind the collimation, the drift of wavelength will cause-1 order diffraction light beam (being the reconstruction beam of collimator graduation image) direction generation marked change, causes pointing error.
Take aim at tool as weapon, must have correcting mechanism, so that in dress rifle post-equalization zero-bit.Alignment clamp shown in Figure 1 is calibrated zero-bit by level and vertical direction rotation hologram sheet 5, and after the hologram sheet rotation, collimated light changes immediately in the incident angle of holographic facet, thereby the reconstruction beam direction of outgoing also changes, and has reached the purpose of calibration.Alignment clamp shown in Figure 2 is calibrated zero-bit by level and vertical direction rotation diffraction grating 10, after grating rotating, collimated light changes immediately in the incident angle of grating face, thereby also change by the parallel beam direction of grating directive hologram sheet, the reconstruction beam direction of outgoing has also obtained calibration.
As the very near Mini Weapon Sight of range, can adorn mark, the target of directing pointing shooting.But the weapon far away slightly to range needs to adorn mark sometimes, i.e. the range setting scale.Though adorn to be marked in theory with above-mentioned correcting mechanism and also be fine, but a cover mechanism finishes the very inconvenience of two kinds of functions, again because the complete western image lines that laser forms are thicker, not very clear, and the angular distance of staff gauge reticle is often nearer, scale directly can't be made in the holographic collimator graduation image.
For above-mentioned range weapon far away slightly, holographic aiming device need solve distance scale and set problem.Because the angular distance of distance scale is nearer, scale directly can't be made in the holographic collimator graduation image, certainly, can adopt the governor motion of pure machinery in the junction of alignment clamp and weapon, whole alignment clamp is regulated with respect to weapon.But mechanism's volume weight of this pure machinery is bigger, and steadiness is also bad.Therefore, existing holographic aiming device all can not address this problem well.

Embodiment
Shown in Fig. 3-8: the laser instrument 12 of holographic aiming device is positioned on the focus of an optical alignment mirror 14, and after the refraction or reflection by collimating mirror 14, the laser beam that laser instrument 12 sends becomes parallel beam.This collimated laser beam is directive diffraction grating 15 at a certain angle, and the directional light that is still a certain angle of outgoing, this light beam be directive hologram sheet 16 at a certain angle again, from the light beam or the directional light of hologram sheet 16 outgoing.The reality that sets of distance scale is exactly the beam direction that changes from hologram sheet 16 outgoing, the present invention is under the constant situation in the position of hologram sheet 16 and diffraction grating 15, two kinds of methods that change the outgoing beam direction of hologram sheet 16 are provided: two of (1) employings and a plurality of different wavelength of laser devices throw light on respectively, the outgoing beam direction of diffraction grating 15 and hologram sheet 16 all can change, suitably select wavelength, can reach dress target purpose; (2) method of the optical axis relative position by changing laser instrument 12 and collimating mirror 14 changes the outgoing beam direction of collimating mirror 14, and the outgoing beam direction of diffraction grating 15 and hologram sheet 16 also can change thereupon, thus the range setting scale.
When adopting two or more different wavelength of laser device 12, can transform with a rotating mirror 13, catoptron turn to some laser instruments 12, the laser beam that this laser instrument 12 sends just enters light path, sees Fig. 3.The wavelength of laser instrument 12 by firing table fixed firing angle value and optical system parameter selected, a firing angle on corresponding firing table of wavelength.
When adopting two or three different wavelength of laser devices 12, can adopt a fixing cemented prism 17 or 18, shown in Figure 4 and 5.Can be coated with partial reflection film or wavelength selectivity reflectance coating on the cemented surface of prism 17,18, the picture of the luminous point of each laser instrument 12 all is positioned on the focus of collimating mirror 14, need set which firing angle, only need get final product laser instrument 12 conductings of respective wavelength.
Because system can only be near achromatism (wavelength is regarded as aberration with variation of temperature) a certain wavelength, so, the pointing accuracy that can only guarantee a firing angle remains unchanged when range of temperature is big substantially, the pointing accuracy of other firing angles may produce more significantly decline when temperature variation is big.And, because achromatic effect, make that when changing the wavelength of laser instrument 12, the light angle between diffraction grating 15 and the hologram sheet 16 changes greatly, but change less from the beam direction of hologram sheet 16 outgoing at last.Therefore, utilize the different laser instrument of wavelength 12 in a small range, to set firing angle.
The method that changes laser instrument 12 positions can make laser instrument 12 along the direction translation vertical with optical axis, sees Fig. 6.The distance of translation is by the value decision of the corresponding angle of firing table.
The method that changes above-mentioned opposite position also can be seen Fig. 7 with a rotating mirror 20 and two or more laser instruments 12 of adjusting in advance.Rotating mirror 20 is folded to each laser instrument 12 to optical axis by rotation, and the luminous point of each laser instrument 12 is adjusted according to table in advance from the distance of optical axis, and each is apart from corresponding firing angle.Rotating mirror 20 can both accurately be located when reflecting optical axis to any one laser instrument 12.
The method that changes above-mentioned relative position can also be seen Fig. 8 with a half-reflecting mirror or prism 21.Catoptron or prism 21 are divided into two-way or three tunnel to the optical axis of collimating mirror 14, and a laser instrument 12 is pointed on each road.The luminous point of each laser instrument 12 is from the value of the corresponding firing angle of distance of axle.The advantage of this method is not have movable members, and reliability is higher.
The used collimating mirror of holographic aiming device 14 general only in very little visual field (approximately ± 10 milliradians) have picture element preferably, corresponding holographic graduation reconstruction beam variable quantity approximately ± 2.5 milliradians.The firing angle that sets if desired is bigger, needs to be equipped with the bigger collimating mirror 14 of apparent field.
Described laser instrument 12 can adopt laser diode or other the similar device that can launch laser.
