Background

The hyperspectral imaging technology is an advanced technology which integrates the fields of photonics, optoelectronics, calculator science, information processing and the like, and is widely applied to various industries.

For a spectral imaging system applied to agriculture and forestry product detection, data fusion often cannot be performed when hyperspectral imaging systems of different wave bands are used for agriculture and forestry product detection, and the data fusion is not possible to be influenced by the pose of a camera. In experiments it was found that when an object is moved from left to right on a conveyor belt, the picture taken by the suspended imager is dispersive and a picture of its side cannot be taken. Repeated tests show that the phenomenon is caused by the fact that optical axis parallax exists between the internal and external push-broom working states, namely, the optical axis must rotate for an angle to obtain the same visual angle as the internal push-broom imaging during external push-broom, and the imaging visual angle during internal push-broom imaging is basically consistent with the optical axis. At present, adjustable supports on the market are all directed at small and medium-sized cameras, rotation in a horizontal plane is mostly realized, and no existing support can be used for solving the problem of optical axis deviation of a hyperspectral imager.

Due to the special structure of the locking pin, the swing angle adjusting disc cannot be in contact with the support, and meanwhile due to the existence of the spring in the locking pin, the spring gives a rightward force to the swing angle adjusting disc, so that the rotating process is more stable.

As the utility model discloses further improve, the pivot angle adjustment disk removes bottom, pinhole portion and concave part, and all the other thickness are between 2mm-4mm, and general thickness is 2mm-4 mm.

The utility model provides a hyperspectral imager clamping device, which has the following advantages;

1) the imager can be stably rotated for a certain angle and fixed;

2) the structure is simple, and the occupied space is small;

3) the swing device achieves the swing purpose, and simultaneously uses the least and simplest parts;

4) the problem of overlarge torque caused by stress of a single damping hinge is solved;

5) this application is at the fitting pin under the effect, the imager neither can overturn left, when angle regulation, also can not bump with the support on the right.
