Infrared spectrogram correlation detection system and method for mobile platform

Abstract

The invention discloses an infrared spectrogram correlation detection system for a mobile platform. The system comprises an optical dome, a broadband optical system, a two-dimensional servo system, an infrared optical fiber, a Fourier interference spectrum module, a spectrogram correlation detection processing module, a power module and a display module. Incident light enters the broadband optical system from the optical dome and is split by a spectroscope; transmitted light is focused on an infrared detector for imaging through a long-wave imaging lens set; reflected light is focused on an optical fiber coupler through a broad-spectrum lens set and enters the Fourier interference spectrum module through the infrared optical fiber to form an interferogram, and Fourier transformation is carried out on the interferogram to form spectral data; the spectrogram correlation detection processing module effectively infuses infrared imaging and the broadband spectral data, controls the center directivity of the broadband optical system through the two-dimensional servo system and then achieves target detection and tracking and spectral measurement under the mobile platform condition. Disturbance of the mobile platform to the system can be effectively isolated, and the system can carry out synchronous scene imaging and local area spectral measurement and multi-target tracking spectral measurement and is high in speed, appropriate in data size and broad in application prospect.
