Disclosed in the present embodiment, the principle of work of visible-infrared bilateral video camera is as described below:
In the present embodiment, when infrared light filter plate moves in light path, when described visible ray filter plate shifts out light path, have infrared light filter plate visible-infrared imaging objective lens 211, far infrared-visible filter plate 212, visible-infrared imaging eyepiece camera lens 213, FPA chip 24, incoherent area array light source 221, collimation lens 222, cube Amici prism 251, Fourier transform lens 252, spectrum filter 253, imaging lens 254 and optical receiver 26 form infrared light light path, this light path can work under night vision function or the faint environment of visible ray, now infrared light passes through by the infrared light filter plate of visible-infrared imaging objective lens 211.Infrared light is carried out transmission by far infrared-visible filter plate 212, utilize visible-infrared imaging eyepiece camera lens 213 in FPA chip 24 imaging, incoherent area source 221 forms pointolite after small filter, the light beam of pointolite is after collimation lens, become collimation parallel beam, being deflected into through cube beamsplitter 251 is mapped on FPA chip 24, because the back side of FPA chip 24 produces thermal effect owing to absorbing infrared light, thus make the reflecting surface based on the semi-girder of bi-material layers can produce the skew of certain angle, therefore, the light beam passing through this reflective surface can produce the skew of certain angle, the frequency spectrum with the light beam of angular deflection received becomes on the frequency plane of spectrum filter 253 position by Fourier transform lens 252, spectrum filter 253 can filter out the light that the frequency reflected from FPA frame part differs from reflecting surface frequency spectrum, and when there is skew in beam angle, because its spectrum position can move along with the change of angle, so also can there is corresponding change by the luminous flux of this wave filter 253 thereupon, thus the light intensity signal causing optical receiver 26 to receive and its reference time point, the image gathered when namely there is not angle change is compared, create gray level change, this gray level is utilized to change, near infrared imaging can be obtained.
When visible ray filter plate moves in light path, when infrared light filter plate shifts out light path, have visible ray filter plate visible-infrared imaging objective lens 211, far infrared-visible filter plate 212, visible-infrared imaging eyepiece camera lens 213, visible band pass filter 231, right-angle reflecting prism 232, cube Amici prism 251, Fourier transform lens 252, imaging lens 254 and optical receiver 26 form visible ray light path.The visible ray filter plate of visible-infrared imaging objective lens 211 passes through visible ray, through visible band pass filter 231 after visible ray reflects via far infrared-visible filter plate 212, retain the visible ray identical with incoherent area array light source wavelength, the visible ray of other wavelength of filtering, after two secondary reflections by right-angle reflecting prism 232 of the visible ray that obtains, be transmitted through cube Amici prism 251, after its reflection, by Fourier transform lens 252, the final imaging on optical receiver 26 of imaging lens 254.
As can be seen from above-mentioned principle of work, above-mentioned two light paths work under varying environment and time period, when carrying out imaging observation in the good situation of light on daytime, then the visible ray filter plate of visible-infrared imaging objective lens 211 are moved into light path; When infrared night viewing function is opened, the infrared light filter plate of visible-infrared imaging objective lens 211 moves into light path, allows infrared ray enter, realizes day and night double vision function by the conversion operations of dual band pass filter plate.
It is dual band pass optical filter that the present embodiment does not limit light-splitting device, and it can also be the device that grating, prism etc. can carry out light splitting.
Based on above-mentioned principle of work, as shown in Figure 3, its basic structure is same as shown in Figure 2 for the structure of as seen another disclosed in the embodiment of the present invention-infrared bilateral video camera, has just carried out corresponding adjustment because the logical light of filter plate is different with reflective frequency range.
In this instructions, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.For device disclosed in embodiment, because it corresponds to the method disclosed in Example, so description is fairly simple, relevant part illustrates see method part.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
