【摘要】：針對紫外通信接收光學(xué)系統(tǒng)的特點(diǎn)和發(fā)展趨勢,在共軸三反光學(xué)系統(tǒng)的基礎(chǔ)上,提出了一種離軸三反紫外光學(xué)系統(tǒng)的設(shè)計方法,利用ZEMAX軟件進(jìn)行優(yōu)化。設(shè)計出了一個焦距為998.192mm、視場角不小于4°、F數(shù)為4的離軸三反光學(xué)系統(tǒng)。在50lp/mm空間頻率處傳函達(dá)到0.4以上,接近衍射極限,全視場彌散斑控制在5μm以內(nèi),同時克服了共軸三反存在的中心遮擋問題,提高了系統(tǒng)的像質(zhì)。該系統(tǒng)設(shè)計滿足相應(yīng)技術(shù)要求,對紫外通信系統(tǒng)的成功研制具有重要作用和意義。
[Abstract]:In view of the characteristics and development trend of ultraviolet communication receiving optical system, a design method of off-axis triple reverse ultraviolet optical system is proposed on the basis of coaxial triple reverse optical system, which is optimized by ZEMAX software. An off-axis three-mirror optical system with a focal length of 998.19mm and an angle of view of not less than 4 擄F is designed. At the spatial frequency of 50lp/mm, the transmission function is more than 0.4, which is close to the diffraction limit, and the total field of view dispersion is controlled within 5 渭 m. At the same time, it overcomes the central occlusion problem and improves the image quality of the system. The design of the system meets the corresponding technical requirements, and has important role and significance for the successful development of ultraviolet communication system.
