The invention discloses a novel self-focusing integrated hyperspectral imaging detection system based on ETL, relates to the technical field of hyperspectral imaging, and solves the problems that in the remote sensing detection process of an existing hyperspectral imager, the defocusing phenomenon is caused by dynamic changes of environmental factors and the stability of a load platform, the self-focusing process of the hyperspectral imager is tedious, the focusing accuracy is low, the detection efficiency is low, and the real-time performance is poor. Ground object radiation information collected by a telescope objective is divided into a hyperspectral imaging light path and an automatic focusing light path through an ETL and a beam splitter prism, the automatic focusing light path is imaged on an area array detector after being reflected by the beam splitter prism, and the hyperspectral imaging light path is imaged on an entrance slit after being transmitted by the beam splitter prism; and the spectral ligh
