Abstract

Multi-spectral Guidance is most important in the development of modern Optical Guidance System. This paper advances a scheme of spectrum-dividing system used in the multi-spectral guidance optical system. The scheme introduces prismatic technology into the design of optical system of the Guidance System. Combining characters of optical thin-films and prisms and optimizing filmy parameters by Simulated annealing algorithm so that it can divide the multi-spectrum into available spectrums completely. Consequently, a miniature, lightweight spectrum-dividing construction, suitable for different wavelengths, has achieved. It satisfies the requirements of a multi-spectral optical guidance system. And the spectrum-dividing system designed in this paper can divide a wide spectrum ranged from 0.4 to 5.0μm into three spectra, which are visible, short-infrared and medium-wave infrared separately. Compared with the traditional guidance system, it can improve the detecting capability effectively.
