Description
Technical field
The present invention relates to the optical target sounding method, particularly a kind of space heterodyne is interfered the Hyper spectral Imaging device and method.
Background technology
Imaging spectral technology adopts radiant image technology and the spectral measurement methods method that combines, and can obtain the two-dimensional space radiation intensity signal of target and the spectral information of target each point.Need to carry out to target the Hyper spectral Imaging detection of inferior nanometer scale in fields such as air pollution detecting, rocket wake flame thermometrics.Existing Hyper spectral Imaging technology mainly is divided into color dispersion-type and interfere type according to the light splitting mode.Need to adopt slit to carry out push-scanning image in the color dispersion-type scheme, the use of slit is so that exist restricting relation between spatial resolution and the luminous flux.In order to obtain high spatial resolution, usually need to reduce the width of slit, and the result causes the very big loss of luminous flux.For the spectrographic detection of weak radiation target, particularly astronomical target, the burden of explorer response sensitivity will be increased.
The interference type super spectrum imager technology is divided into spatial modulation type and image plane interference type.The existing space modulation type interferes the ultraphotic spectral technology to mainly contain two kinds, and a kind of method is to realize by increase dispersing prism in the interference with common path light path; Another kind method is to adopt spatial heterodyne spectroscopy.Although two kinds of methods adopt different optical interference circuits, but basic thought all is to adopt dispersion element under existing optical interference circuit condition, light wave to different wave numbers carries out spatial modulation, thereby obtains the interference signal that is different from the conventional interference spectrometer, and then improves the recovered light spectral resolution.
Wherein, in the interference with common path light path, increase the method that dispersing prism improves spectral resolution, proposed first by people such as Okamoto, be optimized by people such as Meigs afterwards.Because the light wave of the different wave numbers refraction angle in dispersing prism is different, therefore the light wave of different wave numbers through the Sagnac lateral shearing beam-splitter after, its shearing displacement changes with wave beam, thereby obtains the interference signal modulated by dispersing prism at detector.By choosing suitable material and the dispersing prism of different-thickness, can improve the spectral resolution in the detecting band.But the method is used for imaging detection and has following problem: (1) is subjected to the restriction of prism dispersion characteristics, in the spectral information that obtains, the spectral resolution at long-wave band place will be far smaller than the spectral resolution at short-wave band place, therefore detecting band is had selectivity; (2) the method can only improve spectral resolution by material and the thickness dual mode that changes dispersing prism, therefore suitable material may occur in actual applications can not selecting, perhaps may need the dispersing prism of significant volume just can reach the spectral resolution of expection; (3) because the introducing of dispersing prism can affect the image quality of instrument, therefore need the complicated image-forming objective lens optical texture of design to come the deficiency of correcting imaging quality.
The concept of spatial heterodyne spectroscopy is set forth in 1971 the earliest, and Dohi and Susuki adopted holofilm to carry out the experimental study of spatial heterodyne spectroscopy as detector at that time.Along with the development of correlation technique, this technology has obtained fast development after the nineties in 20th century.Nineteen ninety, the J.Harlander of the U.S. and F.L.Roesler begin to adopt ccd detector to carry out practical SHS research.1991, J.Harlander obtained the attention of the units such as USN, NASA after setting up first space heterodyne spectrographic laboratory model machine immediately, and head obtains support in interspace dark matter detection and atmosphere hydroxyl on the middle and senior level detection.1999, the people such as B.W.Smith began to carry out the design studies work of infrared (8～12 μ m) space heterodyne spectrograph.Compare with the conventional interference imaging spectral technology, spatial heterodyne spectroscopy has the ability of obtaining ultrahigh resolution spectrum in than the small band scope, the technical fields such as astrosurveillance, atmospheric remote sensing have been applied at present, but the existing space heterodyne spectral technique supposition detection of a target has evenly unified spectral distribution, therefore being mainly used in the single-point target imaging surveys, not yet be embodied as the picture spectrographic detection, limited the application of this technology.
