Description
Technical field
The utility model relates to a kind of image capturing system, and is especially a kind of based on day blind ultraviolet, thermal infrared and the multispectral image acquisition system of visible light/low-light.
Background technology
At present, the monitoring in a lot of fields all is that carry out on the basis with the optical instrument.Based on optical instrument, can carry out from the ultraviolet to the visible light again to the detection of the very big wavelength coverage of infrared band, can be used for monitoring various problems.
Single wave band imaging technique in the prior art as visual light imaging technology, low-light level imaging technology, thermal infrared imaging technology, day blind ultraviolet imagery technology etc., has its special application direction separately, has the irreplaceable advantage of other imaging means respectively.Wherein day blind ultraviolet imagery technology is as a kind of emerging high-tech technology, can be the solar blind UV imaging of 190nm-285nm wave band and be not subjected to the influence of inclement weather environment such as sunlight background, misty rain fully to wavelength coverage, and detectable distance, detection sensitivity height, advantage is very obvious in the application in a lot of fields.As in the power grid security malfunction monitoring: can monitor the solar blind UV that the fault zone produces because of corona discharge by blind ultraviolet imagery technology of day, and distinguish failure problems with this.With day blind ultraviolet monitoring can the discovering device initial failure, be convenient to timely maintenance; Infrared monitoring differentiates by the temperature variation of monitoring power equipment mainly whether working properly it is, but the infrared background complexity, and detected fault belongs to middle and advanced stage; Visible light monitoring is the surface imperfection by common security monitoring product (as common camera) imaging picture discovering device and stained then, generally, all belongs to late-in-life failure by the equipment failure of visible light discovery.And these three kinds of optical monitoring methods have almost covered all electrical network optical monitoring means, if it can be synchronized in the same monitoring system, be combined into a multispectral section imaging system, can catch the optical signature of power grid security fault to greatest extent, comprehensive diagnostic electric network fault point satisfies the electrical network actual demand.
Use multiband imaging technique (especially thermal infrared and its all band) at present when simultaneously same target scene being carried out imaging, because it is widely different to the requirement (as detector kind, optical material etc.) of optical imaging system during the photoimaging of different-waveband, if optical system of design, its service band is cover heating infrared band, day blind ultraviolet band and visible light wave range simultaneously, and make the imaging no parallax, not only expend cost, technically even be difficult to realize.Thereby when in the existing technology Same Scene being carried out the imaging simultaneously of a plurality of wave bands, often different types of imaging channel alignment target scene is carried out independent imaging, but the image that obtains separately like this can be directly synthetic because of parallax inconvenience.Therefore how designing an optical system can all be a technical barrier simultaneously to the parallax free multi-band image of same scene, also synthetic output all the time.
Chinese invention patent instructions CN 102323670 A disclose a kind of ultraviolet, visible light and near infrared triband optical imaging system.Its service band is respectively: 0.30-0.38 μ m of ultraviolet band; 0.40-0.65 μ m of visible light wave range; 0.76-1.0 μ m of near-infrared band.This system comprises glass window, triband Amici prism, ultraviolet band system, visible light wave range system and near-infrared band system.During its work, target beam is transmitted through the triband Amici prism through glass window, the first cemented surface light reflection ultraviolet bundle of described triband Amici prism, visible light transmissive light beam and near infrared light beam, the ultraviolet light beam of this reflection is incident to the ultraviolet band system, forms the ultraviolet band image; The visible light beam of transmission and near infrared light beam are incident to second cemented surface of triband Amici prism, the described second cemented surface reflect visible light light beam, transmission near infrared light beam, the visible light beam of this reflection is incident to the visible light wave range system, form the visible light wave range image, and the near infrared light beam of transmission is incident to the near-infrared band system, forms the near-infrared band image.
The disclosed system of above-mentioned instructions can obtain the image information of target three wave bands in 0.3-1.0 mum wavelength scopes of synchronization.But the ultraviolet band that adopts the near-infrared band of 0.76-1.0 μ m and 0.30-0.38 μ m during its imaging often can not practical requirement, because heat source position can't be sensitively surveyed in the near-infrared band imaging.And it is bigger that the ultraviolet imagery of 0.30-0.38 μ m is influenced by sun background etc., be unfavorable for sunlight by day strong situation under use, a day blind ultraviolet band imaging then can overcome these shortcomings.Therefore the described structure of this system can not realize multispectral section imaging system of a kind of day blind ultraviolet band, visible light wave range and thermal infrared wave band, and its all component all needs to design voluntarily, not only realizes difficulty but also cost height.
