Description
Technical field
The utility model relates to light source field, relates in particular to a kind of push-broom type high light spectrum image-forming with wide spectrum uniform line illuminating light source device.
Background technology
As everyone knows, spectrum analysis is a kind of important research means in the natural science, and spectral technique can detect indexs such as the physical arrangement, chemical composition of testee.Spectral assessment is based on point measurement, and image measurement is based on the spatial character variation, and both respectively have its pluses and minuses.Therefore, we can say that the light spectrum image-forming technology is the inevitable outcome of spectral analysis technique and image analysis technology development, is the product of the two perfect adaptation.The light spectrum image-forming technology not only has spectrally resolved ability, also has the image resolution ability, utilizes the light spectrum image-forming technology not only can carry out qualitative and quantitative analysis to examined object, and can also advance it is positioned analysis.
The main working parts of Hyperspectral imager is an imaging spectrometer; It is a kind of novel sensor; Early 1980s formally begins development, and the purpose of developing this quasi-instrument is for obtaining a large amount of narrow wave band continuous spectrum view data, making each pixel have subcontinuous spectroscopic data.It is the optical imagery at a series of optical wavelengths place, comprises tens of hundreds of wave bands that arrive usually, and spectral resolution is generally 1～10nm.Because the high spectrum image that high light spectrum image-forming obtained can provide a subcontinuous curve of spectrum to each pixel in the image; It obtains can obtain again than multispectral more horn of plenty spectroscopic data information in the spatial information on determinand; These data messages can be used to generate complex model, differentiate, the material in the classification, recognition image.
The high light spectrum image-forming device generally is made up of three parts at present: imaging lens, imaging spectrometer, planar array detector (like the CCD camera).A herring bone of two-dimensional bodies is through the imaging lens imaging and through the preposition slit of spectrometer; Light becomes after through one group of lens perpendicular to the directional light on the slit direction then; This directional light through the transmission grating in the spectrometer perpendicular to slit direction generation chromatic dispersion; Become the monochromatic light that launches with wavelength perpendicular to the direction of slit direction, the monochromatic light that launch perpendicular to slit direction on this edge passes through last group lens imaging of spectrometer to the area array CCD detector.What therefore the area array CCD single detected is the spectrum of a herring bone object, is characterized in being parallel to the intensity profile that slit direction is the herring bone object, and is the expansion of picture on spectrum perpendicular to slit direction.
Therefore, if accomplish light spectrum image-forming to two-dimensional bodies, need be with object along doing one-dimensional scanning perpendicular to the relative imaging spectrometer of slit direction, each herring bone is formed images successively then is spliced into two dimensional image.
Prior art realizes the even line style illumination to object through the output of the even line style light belt of linear array arranging light emitting diode (LED) realization.But the spectral region of LED is narrower, has only the spectral width of tens nanometers usually, and high light spectrum image-forming can realize that hundreds of arrives the light spectrum image-forming of thousands of nanometers usually, therefore can't satisfy the demand of high light spectrum image-forming for wide spectral range.
Prior art is bonded to linear optical fiber with the broad spectrum light source lotus root, shines through optical fiber and realizes wide spectrum line style illumination on the sample.But optical fiber output energy is lower, and fiber optic materials is lower at infrared transmittivity, can't use to 2500 nano spectral scopes in 1700 nanometers.
