Embodiment
To make the purpose of the present invention, content and advantage clearer, with reference to the accompanying drawings and examples, to the tool of the present invention
Body embodiment is described in further detail.
To adapt to the application demand of the airborne multiband high light spectrum image-forming of integration, the present embodiment proposes a kind of airborne multiband
High light spectrum image-forming spectrometer opto-mechanical interface, the interface are used to the terrestrial information light of collection optical system being transferred into imaging spectral
Instrument.
The opto-mechanical interface is stiffener plate structure, as shown in Fig. 2 being offered in stiffener plate 1 and imaging spectrometer
Multiple light holes 2 corresponding to each image-forming module, the quantity of light hole 2 are determined by the quantity of imaging spectrometer image-forming module.It is logical
The thang-kng size of unthreaded hole 2 is obtained by each image-forming module peripheral field imaging light in the trace position of opto-mechanical interface, by being imaged
The difference of spectrometer visual field can be set to rectangle (trapezoidal) or circular (ellipse), the size in hole by optical system visual field (FOV)
And the distance of position of opening to object lens determines.The distribution of light hole 2 determines by distribution of each image-forming module in opto-mechanical interface, its point
Cloth depends on the volume and weight of each image-forming module.
