Abstract

The invention provides an infrared image generating device and method based on an optical filter color wheel, mainly applied to semi-physical simulation of a missile guidance system. The infrared image generating device based on the optical filter color wheel comprises an optical filter color wheel module (2), a synchronous collimation module, a spatial light modulation module (5) and an imaging module (6); wherein the optical filter color wheel module (2) and the spatial light modulation module (5) are core modules, and the analog output of an infrared multi-spectral dynamic scene image is completed by time-sharing simulation of a single spectrum segment. The invention can realize single-source single-channel infrared image composite output, and has the advantages of simple principle, less spectral distortion and no aliasing of the spectrum.

Description

technical field [0001] The present invention relates to the field of guidance system simulation, in particular to an infrared image generation device and method based on a color filter color wheel, and in particular to an infrared multispectral image generation device and method based on a color filter color wheel. Background technique [0002] Traditional infrared guidance systems are easily affected by infrared decoys, background heat radiation and climate. With the development of intelligent and suppressed infrared decoys, traditional infrared guidance methods are difficult to adapt to the modern battlefield environment. Infrared multi-spectral imaging guidance technology has technical advantages in target recognition and suppression of background clutter. Multi-spectral imaging technology is an information acquisition technology that integrates maps and spectra. It can not only obtain geometric shape information of imaging targets, but also identify targets. Differences ...
