Background technology
In life science and material science research field, the optical imagery instrument is the important means of observation and analyzing samples.These optical imagery instruments comprise biological microscope, fluorescent microscope, stereomicroscope, inverted microscope, metaloscope etc. at microcosmic imaging side face; Comprise monochromatic digital image-forming instrument, colored digital imager, infrared thermoviewer, pickup camera etc. at macroscopical imaging side face.These optical imagery instruments can only carry out gray scale or colour imaging to detecting target, use image processing and pattern recognition that target is carried out analysis on the morphosis then.Along with the needs of the development and the research of technology, when sample is carried out check and analysis, except will carrying out the morphological analysis, also require sometimes its biological chemistry is changed and composition carries out Quantitative study to it, promptly target is carried out the chemical imaging analysis.
At life science, existing biochemical analysis method is by means of all ingredients on the one hand, is to use special-purpose functional image equipment on the one hand.These special-purpose functional image functions of the equipments are single relatively and cost an arm and a leg, and dirigibility is relatively poor.The Hyper spectral Imaging technology is applied to the remote sensing field at first, at aspects such as geology, agricultural, vegetation, environment, city, military affairs, the hydrology, atmosphere good application is arranged all.Analysis as if this technology being applied to sample then can realize form and biochemical analysis simultaneously, carries out the description of qualitative, quantitative and location to detecting target, thereby realizes the early diagnosis to some pathological change.Population health level and people's living standard are significant for improving.At material science, can only obtain the technology of object construction information compares with ordinary optical microscope, Electronic Speculum, AFM etc., the light spectrum image-forming technology not only can be analyzed with quantification the surface structure information of material and describe, can also accurately discern and analyze the constituent of material, and combined with intelligent discriminance analysis algorithm realizes the distribution and the situation of change of different compositions, and material is carried out more meticulous sign.
Though the light spectrum image-forming technology has good prospects for application in fields such as life science and material science, but owing to existing optical spectrum imagers all are dedicated system of developing at a certain concrete goal in research, can not with these fields in be coupled at the optical detection apparatus that uses, so this technology is not also in these field widespread uses.
Summary of the invention
The objective of the invention is to overcome the light spectrum image-forming technology uses in fields such as life science and material science and has the problem that optical instrument combines difficulty now, provide a kind of standard interface that has, the general hyperspectral imaging component that can be well is coupled and uses with existing optical detecting instrument such as microscope, camera etc.This general hyperspectral imaging component uses the standard interface of C-Mount as imaging, use general chromatic dispersion unit that the reflected light or the transmitted light of optical instrument are carried out beam split, use charge-coupled device (CCD) to carry out the record of data, once gather the information that promptly can obtain observed object image and spectrum two aspects simultaneously, handle through the Intelligent Recognition analysis software again, promptly can obtain than existing optical detecting instrument more sample information.By using this general hyperspectral imaging component, can expand existing optical detecting instrument and use widely.
The object of the present invention is achieved like this:
A kind of general hyperspectral imaging component, comprise C-Mount interface, collimating mirror, chromatic dispersion unit, convergent mirror, CCD, data acquisition and control module, telecommunication cable and computing machine, characteristics are that C-Mount interface, collimating mirror, chromatic dispersion unit, convergent mirror, CCD become light path to connect successively; The reflected light of optical instrument or transmitted light arrive the chromatic dispersion unit through collimating mirror after being coupled through the C-Mount interface, and the light of process chromatic dispersion unit chromatic dispersion images on the CCD through behind the convergent mirror; The data output cable of CCD is connected to data acquisition and control module, and the umbilical cable of data acquisition and control module is connected to the chromatic dispersion unit, the beam split work of control chromatic dispersion unit; The output cable of data acquisition and control module is connected to computing machine, and the ultraphotic spectrum data transmission of gathering is handled to computing machine.
By the image of continuous acquisition optical instrument, can obtain hyperspectral image data in the optical instrument visual field at last, i.e. the image cube at different wave length.This image cube had both comprised the view data of optical instrument institute observation sample, had also comprised its spectral information.These data transmission are handled and analyzed to computing machine, promptly can realize sample is carried out form and biochemical analysis simultaneously, thereby expanded the function of existing optical detecting instrument.
Above-mentioned optical instrument is the detecting instrument with C-Mount standard interface, as all kinds of microscopes, industrial camera etc.; Described chromatic dispersion unit can be elements such as acousto-optic tunable wave filter (AOTF), liquid crystal tunable filter (LCTF), arc prism spectrometer or grating; Be connected data cables such as to use serial communication RS232, general-purpose serial bus USB or netting twine between data acquisition and control module and the computing machine.
General hyperspectral imaging component of the present invention has the C-Mount standard interface, can be coupled with the universal optical instrument, has expanded its check and analysis function.Have good versatility and practicality.
