Embodiment
In order to make purpose of the present invention, technical scheme and advantage more cheer and bright, below in conjunction with drawings and Examples, the present invention is described in detail.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
In the market used hand-held binary channels day blind ultraviolet imagery instrument structure mostly as shown in Figure 1, its inner integrated day blind ultraviolet imagery module, reference background image-forming module (as visual light imaging module, infrared light image-forming module etc.), relevant treatment chip and display module etc. are in one, some kilograms (being generally about 3.5kg) so weight all can weigh.When reality was used, people had to reduce accordingly its visual field in order to improve the shooting sensitivity of day blind ultraviolet imagery instrument.Because target occasion situation differs, the staff often imager need be raised certain angle with the circuit of aiming at eminence or constantly adjustment equipment point to aim at the mark, therefore need raise the equipment of loweing continually or adjustment equipment is controlled posture.This is bigger for the track walker's physical load that works long hours.
The present invention overcomes above-mentioned difficulties by scanning reflection mirror is installed before the imager camera lens on the basis of blind ultraviolet imagery instrument of existing binary channels day.
Referring to Fig. 2, be the embodiment of the invention 1 described binary channels day blind ultraviolet imagery instrument structural drawing that carries out visual field scanning, it comprises scanning reflection mirror 1, catoptron 2, binary channels day blind ultraviolet imagery instrument 3 and rotating shaft 4.The staff can pass through front and back rotary scanning catoptron 1 in when operation, makes the target light signal change 1 and after catoptron 2 reflects through scanning reflection mirror, enters blind ultraviolet imagery instrument 3 imagings of binary channels day.The binary channels day of adopting this that scanning reflection mirror structure is installed blind ultraviolet imagery instrument, can avoid the personnel of patrolling and examining to raise the posture of controlling of the equipment of loweing or adjustment entire equipment continually, the scanning reflection mirror 1 that as long as it rotate wherein can realize that the bigger corona in visual field detects on the vertical direction.
Referring to Fig. 2, the camera lens 3-1 in scanning reflection mirror 1, catoptron 2 and the binary channels day blind ultraviolet imagery instrument 3 is arranged in order in the direction of propagation of light, and three's meridian ellipse overlaps.Scanning reflection mirror 1 is installed on the front upper place of camera lens 3-1 by rotating shaft 4, the size of scanning reflection mirror 1 and position should be satisfied, when it rotates in catoptron 2 orthogonal projection of imaging in plane, camera lens 3-1 place all the time fully coupling cover camera lens 3-1, preferably, scanning reflection mirror 1 is in rotation process, and the angle of the chief ray between scanning reflection mirror 1 and the catoptron 2 changes between 15 ° to 45 °.Rotating shaft 4 is vertical with the meridian ellipse of camera lens 3-1.Using described binary channels day of carrying out visual field scanning of present embodiment during blind ultraviolet imagery instrument, rotary scanning catoptron 1 before and after operating personnel only need, can carry out visual field scanning, this moment, the target light signal by blind ultraviolet imagery instrument 3 imagings of binary channels day, did not need operating personnel to raise frequently to lower imager or front and back to rotate whole imaging device through scanning reflection mirror 1 and catoptron 2 reflection backs.
Catoptron 2 is fixedly installed in the front lower place of camera lens 3-1 in the blind ultraviolet imagery instrument 3 of binary channels day, not rotatable, its reflecting surface is towards camera lens 3-1, and the size of catoptron 2 and position should be satisfied its orthogonal projection in plane, camera lens 3-1 place at least and be mated covering camera lens 3-1 fully.Preferably, the angle between the primary optical axis of catoptron 2 and camera lens 3-1 is performance and the dimensional requirement to take into account system between 40 ° ~ 60 °, and the distance between catoptron 2 and the camera lens 3-1 can be selected according to actual needs at this moment.
Scanning reflection mirror 1 is coated with aluminizing of diaphragm or silvered mirror with catoptron 2 for front surface, and preferred, this diaphragm is the magnesium fluoride diaphragm.Wherein aluminium and silver to day blind ultraviolet have high reflectance to visible light wave range, diaphragm when protection aluminium or ag material are not oxidized to day blind ultraviolet have high permeability to visible light wave range.
Binary channels day, blind ultraviolet imagery instrument 3 was for using more hand-held day blind ultraviolet binary channels imager in the market, the ZF-S1 type binary channels corona monitor of producing as Jiangsu Zi Feng Electro-optical Technology, INC. (US) 62 Martin Road, Concord, Massachusetts 017, Israel Ofil company produces binary channels day blind ultraviolet imagery instrument etc.Target light signal (corona send light signal) as shown in FIG. is imaged and enters day blind ultraviolet imagery passage and visual light imaging passage respectively after spectroscope in the instrument is divided into two bundles, the visual light imaging passage to targeted environment imaging think that a day blind ultraviolet image provides reference background information clearly, day, blind ultraviolet imagery passage carried out imaging to the light signal that corona sends, and the two carries out image stack output in disposal system.
In further embodiment, the catoptron 2 that said fixing is installed in the blind ultraviolet imagery instrument 3 of binary channels day is right-angle prism, and its structure is referring to Fig. 3, comprises scanning reflection mirror 1, right-angle prism 2, binary channels day blind ultraviolet imagery instrument 3 and rotating shaft 4.Wherein scanning reflection mirror 1, binary channels day blind ultraviolet imagery instrument 3 and rotating shaft 4 identical with the above-mentioned blind ultraviolet imagery instrument of binary channels day that carries out visual field scanning.A right-angle plane of right-angle prism is perpendicular to the primary optical axis of camera lens 3-1, the sagittal surface angle at 45 of the inclined-plane of right-angle prism and camera lens 3-1, and its size should satisfy its orthogonal projection in plane, camera lens 3-1 place at least and mate fully and cover camera lens 3-1.Right-angle prism is quartzy material, to reflect solar blind UV and visible light simultaneously.It is because compare with normal mirror that catoptron 2 adopts right-angle prism, the easier installation of right-angle prism and debugging, and the relative normal mirror of reflection angle is also more stable.
