Below by specific embodiment, total-reflection type broadband multi-optical spectrum imaging system provided by the invention is carried out detailed
Explanation.
As shown in Fig. 2, the present invention provides a kind of total-reflection type broadband multi-optical spectrum imaging system, including preposition it is reflected into
As objective system 61, reflection, which filters, to be passed at as system 62, focal plane array detector system 63, optical filtering control system 64 and data
Reason system 65.
The operation principle of total-reflection type broadband multi-optical spectrum imaging system of the present invention is：Target image is reflected by preposition
As after objective system 61, imaging passes the object plane as system 62 to reflection optical filtering；Reflection filters to pass and filters and pass as system 62 has
As dual function, the target optical spectrum image after being filtered will can be transferred to focal plane array detector system 63, utilize optical filtering
Control system 64 changes filtered light image spectrum channel；It is different after being used in combination focal plane array detector system 63 to receive optical filtering successively
Optical image series；The optical image series carry out spectral reflectance recovery by data processing system 65, ultimately form target
Spectral image cube, can therefrom extract the two-dimension spectrum image information of target and one-dimensional spectral information.
For preposition catoptric imaging objective system 61 using the double anti-mirror structures of modified Cassegrain, two reflectings surface are spherical surface,
It is easy to process, and save cost；The relative position of two speculums can be adjusted along optical axis, to realize focus function.
Reflection, which filters, to be passed as system 62 is similar to tri- anti-mirror structures of Ao Funa, by two same oculo cardiac reflex of primary mirror 62-1 and secondary mirror 62-2
Spherical surface forms.Object, the centre of sphere and as three is located along the same line, and object and as symmetrical about the centre of sphere, between image center
Distance D is：
Wherein r1For primary mirror 62-1 spherical radius, r2For secondary mirror 62-2 spherical radius.
As shown in figure 3, the different zones in secondary mirror 62-2 plate different spectral reflectivity films.The spherical surface of secondary mirror 62-2 is equal
It is divided into the six small sphere of exterior rearview regions a-f, the spectral reflectance in each region is designed using spectral reflectivity vector maximum linear independence method
Rate, and according to the spectral reflectivity of design vector, plated film is distinguished to six regions a-f.Reflection filter is realized to secondary mirror 62-2 plated films
The function of light, and the optical texture of primary mirror 62-1 and secondary mirror 62-2 realize the function of passing picture.Therefore, reflection, which filters, passes as system 62
With optical filtering and pass as dual function.
In the embodiment of the present invention, the operating wavelength range for being totally reflected broadband multi-optical spectrum imaging system is limited to visible light
Wave band can plate visible light broadband high-reflecting film on the secondary mirror of preposition catoptric imaging objective system 61, and the film layer is in visible light wave range
Spectral reflectivity average value more than 96%, be less than 3% in ultraviolet and near infrared band average reflectance, to inhibit ultraviolet
With the interference and influence of near infrared light.
Reflection is filtered to pass and is placed on rotating platform 64-1 as the secondary mirror 62-2 of system 62, the centre of sphere of secondary mirror 62-2 is rotating
In the shaft of platform 64-1；By the rotation of filter control and processing module 64-2 control turntables 64-1, keep secondary mirror 62-2 different
Region reflective optical filtering passes the light as 62 primary mirror 62-1 of system, to which the target image of different spectrum channels is transferred to coke
Planar array detector system 63.Optical filtering purpose is realized around the rotation of the centre of sphere, whole system is made to be easy to adjustment using secondary mirror 62-2,
And its system stability is higher；And it is the picture that entire imaging system introduces that reflective optical filtering, which effectively prevents transmission filter element,
Difference and aberration.The control that filters has hardware synchronizer with processing module 64-2 and focal plane array detector system 63, to protect
After card secondary mirror 62-1 is rotated in place, this collected channel spectrum image of focal plane array detector system 63 is effective.
In the present embodiment, it is seen that colored CCD detector array can be used in optical range focal plane array detector system 63, as
First quantity is 1024*1024, and material is thus formed reflection optical filterings to pass the series connection optical filtering system to filter as system 62 and CCD itself RGB
System, can obtain the spectral image data in 6*3=18 channel.If system service band is in non-visible light range, it is necessary to use
The quantity of monochromatic area array CCD detector, spectrum channel is 6.
In the present embodiment, the picture of target is focused on the image planes position of preposition catoptric imaging objective system 61, can be along optical axis
Adjust the relative position of 61 primary mirror 61-1 and secondary mirror 61-2 of preposition catoptric imaging objective system, change image planes position and clearly at
Picture.The image planes position of preposition catoptric imaging objective system 61 is the object plane position for reflecting and filtering and passing as system 62, and reflection filters
It passes as the spectrum picture of different spectrum channels is sequentially delivered to carry out spectrum picture on focal plane array detector 63 by system 62
Sequence acquisition.After the light of target image enters preposition catoptric imaging objective system 61, through preposition catoptric imaging objective system 61
Primary mirror 61-1 reflection light beam reflected by its second speculum after, by the center hole of primary mirror 61-1, focal imaging is to preceding
Set the image planes of catoptric imaging objective system 61.After the light sent out by the image planes enters reflection optical filtering biography as system 62, primary mirror 62-
1 reflection this light beam reflexes to primary mirror 62-1 to being partitioned on the secondary mirror 62-2 of domain plated film, then by secondary mirror 62-2, finally by primary mirror
Imaging to reflection optical filtering passes the image planes position as system after 62-1 reflections, and in this image planes position focal plane array detector system
System 63 receives the spectral image data in this channel, controls secondary mirror 62-2 optical filtering reflector spaces by optical filtering control system 4, you can profit
It receives the spectral image data in each channel successively with focal plane array detector system 63, and obtains optical image series, the light
Image sequence is composed after data processing system 65 carries out spectral reflectance recovery, the spectroscopic data that can finally obtain target image is vertical
Cube, so as to the two-dimensional image information for extracting target and one-dimensional spectral information.
Although being example purpose, the preferred embodiment of the present invention is had been disclosed for, those skilled in the art will recognize
Various improvement, increase and substitution are also possible.Therefore, the scope of the present invention is worked as and is not limited to the above embodiments.
