Infrared imaging spectral measurement system based on gradual filter

The invention discloses an infrared imaging spectral measurement system based on a gradual filter and specifically relates to the technical field of spectral data measurement. The infrared imaging spectral measurement system solves a problem that a conventional imaging spectral system is poor in spectral resolution, has spectral line bending and spectral line color distortion, highly requires design, processing, and adjustment precision, and is high in price. The infrared imaging spectral measurement system based on a gradual filter comprises a control and signal processing module, a prepositioned optical system, a light splitting imaging module, a micro filter and detector module, a signal detection and data acquisition module, a data preprocessing module, and an information processing unit, wherein the prepositioned optical system, the light splitting imaging module, and the micro filter and detector module are disposed successively, and the signal detection and data acquisition module, the data preprocessing module, and the information processing unit are in signal connection.
