英文摘要	This paper details the design of a light airborne imaging spectrometer in order to improve real-time monitoring of natural disasters. This deisgn is based on a lightweight concept, and focuses on the adaptability of the spectrometer in varied environments. First, the optomechanical support structure of the spectrometer were designed by using filter spectrometry, push-broom imaging method and topology optimization, based on the design principles of optimal optical parameters and light weight. Next, a finite element model of the structure was used to analyze the linear static structure, the natural vibrational characteristics, the strength, the optical lens deformation and the modal frequency. Finally, the spectrometer was tested for surface accuracy detection via field experiments. The experimental results show that the ground phase element resolution of the spectrometer is 0.5 m/ km , the size is 175 x 175 x 175 mm, and the machine structure weight is 1.15 kg . The optical machine structure strength and the deformation of the optical lens exceed the target requirements, with a first order modal frequency of 590.8 Hz . The drone can maintain good performance in the temperature range of 0 similar to 40 degrees C with wind conditions less than or equal to 7 and a cruising speed of 100 km/ h.
