Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only some embodiments of the present application rather than whole embodiments wholely.Based on
Embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained, broadly fall into the application protection
Scope.
Referring to Fig. 1, for the structural representation of spectral imaging analysis system embodiment of the present invention.
In the present embodiment, this spectral imaging analysis system, including: liquid crystal tunable filter module 11, at least two
Light source 12, workbench 13, control chamber 14 and computer 15.
Wherein, liquid crystal tunable filter module 11 includes the imageing sensor 111 being sequentially connected with, automatically becomes focus lens
112 and liquid crystal tunable filter optical module 113, to form accurate optical imaging system.
This imageing sensor 111 communicates to connect with computer 15, for generating image corresponding to checking matter and by image
Send computer 15 to；Automatically become focus lens 112 to communicate to connect with computer 15, to realize being answered by preset in computer
It is adjusted with to the focusing and zoom automatically becoming focus lens 112；Liquid crystal tunable filter optical module 113 and control chamber
In 14, liquid crystal tunable filter driver 142 communicates to connect, and control chamber 14 communicates to connect with computer 15, in order to Yong Hu
In the preset application of computer 15, the filtering band value to liquid crystal tunable filter optical module 113 is adjusted and sends to
Control chamber 14, then by control chamber 14 according to receiving what liquid crystal tunable filter optical module 113 was worked by filtering band value
Filtering wave band is controlled.
Concrete, checking matter, can be based on after by the irradiation back reflection of light source to liquid crystal tunable filter module 11
The filtering wave band of the liquid crystal tunable filter optical module 113 determined and the zoom and the focusing that automatically become focus lens 112, logical
Cross imageing sensor 111 generate image corresponding to checking matter and be sent to computer.
Further, imageing sensor can be Scientific Grade black and white charge coupled cell (CCD, Charge-coupled
Device) imageing sensor；Automatically become in focus lens and can be provided with micro-stepping motors, preferably to carry out according to real image
Autozoom and focusing；Liquid crystal tunable filter optical module can be the tune for incident spectrum carries out nano-precision
The liquid crystal tunable filter (LCTF, Liquid Crystal Tunable Filte) that humorous filtering controls.
In liquid crystal tunable filter module 11, imageing sensor 111, automatically change focus lens 112 and liquid crystal tunable
Humorous filter optical module 113 can be configured with the following two kinds structure.
