Abstract: The present invention discloses a moving platform infrared image-spectrum associated detection system, including an optical hood, a broadband optical system, a two-dimensional servo system, an infrared optical fiber, a Fourier interference spectrum module, an image-spectrum associated detection processing module, a power supply module, and a display module. Incident light enters from the optical hood to the broadband optical system, and is split by a spectroscope. Transmitted light is focused by a long-wave imaging lens group on an infrared detector for imaging. Reflected light is focused by a broadband spectrum lens group to an optical fiber coupler, enters the Fourier interference spectrum module through the infrared optical fiber to form an interference pattern, and undergoes Fourier transform to obtain spectral data. The image-spectrum associated detection processing module effectively merges infrared imaging and broadband spectral data, and the two-dimensional servo system is used to control a center orientation of the broadband optical system, thereby implementing target detection, tracking and spectrum measurement in a moving platform condition. The present invention can effectively isolate the system from disturbance of the moving platform, has the capability of simultaneously performing scene imaging, local area spectrum measurement, and multi-target tracking spectrum measurement, has a high speed and an adequate data amount, and has a broad application prospect.
