| Abstract: | In this paper,the advantages of diffractive optical elements are introduced The applications of diffractive elements in surveillances,fire control and photoelectric sight systems are also discussed. An infrared optical system is taken for example. A diffractive optical element is used to eliminate the influence of the temperature change. The image quality comparison between refractive/diffractive hybrid optical system and optical system without diffractive elements was made. The results show that the diffra... |
