【摘要】：采用微進(jìn)多空間多焦點(diǎn)自由曲面鏡頭與成像面的設(shè)計(jì)方法,設(shè)計(jì)了卡塞格林望遠(yuǎn)鏡的鏡頭與成像結(jié)構(gòu);建立了激光雷達(dá)鏡頭與成像面的微分方程,解出自由曲面光焦度變化曲線圖;采用反求工程中的自由曲面重構(gòu)技術(shù),通過(guò)離散曲面的離散數(shù)值解法,獲得了自由曲面的鏡頭與成像面三維數(shù)值,進(jìn)行了自由曲面光學(xué)(FFO,free from optics)鏡頭與成像面離散重建;研制了海星形海底小型激光雷達(dá)系統(tǒng)。實(shí)驗(yàn)結(jié)果表明,系統(tǒng)整機(jī)實(shí)現(xiàn)了全景探測(cè),解決了海底水域的設(shè)施與異物的探測(cè)與監(jiān)測(cè)的難題。
[Abstract]:The lens and imaging structure of Cassegrin telescope is designed by using the design method of micro-entry multi-space and multi-focus free-form surface lens and image surface. The differential equation between Lidar lens and imaging plane is established, and the curve of free-form surface focusing is obtained. By using the technique of reconstruction of free-form surface in reverse engineering and the discrete numerical solution of discrete surface, the three-dimensional numerical value of lens and image surface of free-form surface is obtained, and the discrete reconstruction of free-form surface optics (FFO,free from optics) lens and image surface) is carried out. A small ocean-starlike laser radar system has been developed. The experimental results show that the whole system realizes panoramic detection and solves the difficult problem of detecting and monitoring the facilities and foreign bodies in the sea-bed waters.
