【摘要】：設(shè)計(jì)了大相對孔徑的三檔變焦光學(xué)系統(tǒng)來監(jiān)控海洋生態(tài)監(jiān)測儀器的工作狀態(tài)。該系統(tǒng)的設(shè)計(jì)通過Zemax軟件實(shí)現(xiàn),總長度為200mm,系統(tǒng)采用6.4mm×4.8mm的CCD感光板,三檔變焦焦距分別為8,14,28mm,變焦過程中相對孔徑為1/1.4,短焦時(shí)最大視場角為52°。最大視場角下,當(dāng)奈奎斯特頻率為42lp/mm時(shí),系統(tǒng)的0視場的調(diào)制傳遞函數(shù)(MTF)值為0.8,0.707視場的平均MTF值為0.7,1視場的平均MTF值達(dá)0.6;10μm范圍內(nèi),幾何包圍能量均在90%;畸變控制在合理的范圍。該系統(tǒng)變焦比高、結(jié)構(gòu)簡單、相對孔徑大,適用于海水中海洋生態(tài)監(jiān)測儀器的監(jiān)控,能夠及時(shí)地反饋海洋生態(tài)監(jiān)測儀器的工作狀態(tài)信息,大大降低了海洋生態(tài)監(jiān)測儀器的維護(hù)成本。
[Abstract]:A three-stage zoom optical system with large relative aperture is designed to monitor the working state of marine ecological monitoring instruments. The design of the system is realized by Zemax software, the total length of the system is 200mm. The system adopts 6.4mm 脳 4.8mm CCD photosensitive board. The three-stage zoom focal length is 814 ~ 28mm, the relative aperture is 1 / 1.4 and the maximum field of view angle is 52 擄when the focus is short. At the maximum viewing angle, when Nyquist frequency is 42lp/mm, the modulation transfer function (MTF) of 0 field of view of the system is 0.8 / 0.707. The average MTF of 0 field of view is 0.710 渭 m, the geometric encircling energy of the system is in the range of 0.60 渭 m, and the distortion is controlled in a reasonable range. The system has the advantages of high focal ratio, simple structure and large relative aperture. It is suitable for the monitoring of marine ecological monitoring instruments in seawater, and can feedback the working state information of marine ecological monitoring instruments in time. The maintenance cost of marine ecological monitoring instruments is greatly reduced.
