Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 3, Figure 4:
A combination gun sight, comprises a holographic diffraction sight 2 and a low-light level night vision device 3.
The design that the utility model adopts is holographic diffraction sight 2 to be placed in to the front end top of low-light level night vision device 3, makes sub-fraction light beam 6 in the hologram sheet outgoing beam of holographic diffraction sight 2 from the place ahead input of low-light level night vision device 3 object lens, for sighting at night.As everyone knows, hologram image feature is exactly: the arbitrary fraction on hologram sheet can form a complete hologram image.Utilize this feature, the sub-fraction light beam that we only take hologram sheet outgoing just can project complete holographic collimator graduation image in low-light level night vision device 3 object lens and go, and forms the aiming graduation at night.And most of area of hologram sheet is all for the slewing on daytime.
According to design of the present utility model, the method that holographic graduation is projected in low-light level night vision device 3 object lens is divided into direct projection and projects two kinds with prism.
Shown in Fig. 3, be direct projective method.Directly projective method makes the bright dipping region 4 of the hologram sheet of holographic diffraction sight 2 partly overlap with the light inlet region 5 of the object lens of low-light level night vision device 3.Overlapping region be generally no more than holographic diffraction sight 2 hologram sheet bright dipping region 4 1/5.Segment beam 6 in overlapping region in the hologram sheet outgoing beam of holographic diffraction sight 2 is directly injected low-light level night vision device 3 object lens, is imaged in the image planes of low-light level night vision device 3, forms the real image of holographic graduation.As long as target overlaps with this real image of holographic graduation by low-light level night vision device 3 imagings, just completed the aiming to target.
As shown in Figure 4, prism projective method is in the hologram sheet outgoing beam of holographic diffraction sight 2, to place a little prism, as rhombic prism 7.Now, holographic diffraction sight 2 can stagger in short transverse mutually with low-light level night vision device 3.The plane of incidence of this rhombic prism 7 is towards holographic diffraction sight 2, and exit facet is towards low-light level night vision device 3; The plane of incidence of rhombic prism 7 is parallel with low-light level night vision device 3 optical axises with holographic diffraction sight 2 optical axises respectively with the normal of exit facet, and the top of the plane of incidence of rhombic prism 7 is positioned at the bright dipping region 4 of the hologram sheet of holographic diffraction sight 2, the bottom of the exit facet of rhombic prism 7 is positioned at the light inlet region 5 of the object lens of low-light level night vision device 3.Like this, the sub-fraction light beam 6 in the hologram sheet outgoing beam of holographic diffraction sight 2 can be by injecting low-light level night vision device 3 object lens after rhombic prism 7 refractions.Prism projective method can reduce the loss of effective aperture as far as possible, is conducive to guarantee to greatest extent both performances of holographic diffraction sight 2 and low-light level night vision device 3.
Prism projective method anaclasis mechanism used can be also a pair of right-angle prism setting up and down 8, as shown in Figure 5, the plane of incidence of right-angle prism 8 is above positioned at the bright dipping region 4 of the hologram sheet of holographic diffraction sight 2, and the exit facet of right-angle prism 8 is below positioned at the light inlet region 5 of the object lens of low-light level night vision device 3.
Prism projective method anaclasis mechanism used can also adopt a pair of catoptron setting up and down 9, as shown in Figure 6, catoptron 9 is above positioned at the bright dipping region 4 of the hologram sheet of holographic diffraction sight 2, and catoptron 9 is below positioned at the light inlet region 5 of the object lens of low-light level night vision device 3.
In the combination gun sight that the utility model provides, low-light level night vision device 3 can be not to be with the low light level viewer that aims at graduation, can be also the lll sight that band aims at graduation.When low-light level night vision device 3 carries graduation, carry when graduation and holographic graduation are assembled in factory and be corrected to and overlap, so, during boresight, only need calibrate one of them graduation, do not need two graduation to calibrate respectively.When low-light level night vision device 3 carries graduation, sighting at night can be closed the power supply of holographic graduation, and a utilization carries graduation and aims at.
