A hyperspectral camera based on a continuously variable film filter and a coating method thereof can solve interference between partial bands of the hyperspectral camera based on the continuously variable film filter. The hyperspectral camera includes: a camera body and a detector chip, wherein a continuously variable film is coated on the detector chip; a semi-transmission half-cut filter is provided in front of the continuously variable film, and a distance between the semi-transmission half-cut filter and the continuously variable film is 0 mm. According to the present invention, the semi-transparent half-cut filter and the detector chip are integrated without any gap therebetween. As a result, optical interference caused by incident light sequentially passing through the semi-transparent half-cut filter and the detector chip is greatly reduced, which can reduce distortion of spectral signals, and finally satisfy wide-band application requirements which can be truly realized based on such technology.

A lens scanning mode hyperspectral imaging system and a rotor unmanned aerial vehicle include: an imaging lens, an imaging spectrometer and a surface array detector arranged in sequence and coaxial to a main optic axis, wherein the imaging spectrometer and the surface array detector are connected and mounted to each other; wherein the lens scanning mode hyperspectral imaging system further includes: a driving device for driving the imaging lens to translate relative to a plane where a slit of the imaging spectrometer is. The hyperspectral imaging system of the present invention overcomes the technical bias in the prior art that the imaging lens must be fixed, and the present invention provides relative motion between the target object and the imaging spectrometer by the lens scanning mode for imaging, which solves the image distortion problem of conventional hyperspectral imaging system using a slit scanning mode or a scanning mode.
