ing at the technical problems of existing unmanned aerial vehicle (UAV)-borne hyperspectral imagers, a compact visible near infrared imaging spectral system is designed. First, an imaging spectrometer and a plane array camera are integrated to design the common optical path. Then, the high frame frequency plane array image is used to invert the position and attitude parameters of the camera. Finally, the high-precision spatial information correction is carried out for the synchronously obtained push and sweep hyperspectral image. The system has a working range is 400--1000 nm, a field of view is 43.6° in the width direction, a field of view is 20.0° in the flight direction, a focal length is 13 mm, and a spectral resolution is better than 2.5 nm. ZEMAX software is used to optimize the design and analysis of the system, and prism-grating prism (PGP) design is used for the spectrometer, which has the characteristics of light weight, low cost, and high resource utilization.
