| description | The invention discloses a foundation airglow imaging instrument used for earthquake prediction and forecasting. The foundation airglow imaging instrument comprises a convergent lens group, a filtering assembly, an image rotation lens assembly and a detector assembly, wherein the convergent lens group is used for converging a large-view-field aperture light beam into a low-angle light beam and emitting the low-angle light beam to the image rotation lens assembly; the image rotation lens assembly comprises a field lens and two image rotation lens groups symmetrically arranged on a light path, the field lens receives the light beam from the convergent lens group and transmits the light to the two image rotation lens groups in sequence, and the light beam passing through the two image rotation lens groups is transmitted into the detector assembly; the filtering assembly is arranged between the image rotation lens groups; and the detector assembly is used for detecting a light beam signal.
