Design of Co-aperture Wide Spectrum Compound Eye Optical System
摘要
为了扩大复眼光学系统的接收光谱,研究了一种可见光、长波红外复眼光学系统.推导了双波段共焦面方程,建立了子眼系统与接收系统的匹配要求.子眼光学系统的工作波段为0.38~0.78 μm和8~12 μm,焦距为5 mm,相对孔径为1:3,视场为10°.两个波段的子眼系统成像位置均为2.92 mm,相邻的两个中心光轴夹角为4.016°,共650个子眼,合并后的视场为90°.接收系统的焦距为4 mm,视场为80°,相对孔径为1:3.子眼系统和接收系统的图像质量良好,在-40~60℃的温度范围内无热差影响.
Abstract
In order to expand the receiving spectrum of the compound eye optical system, a visible light and long wave infrared wide spectrum compound eye optical system was studied. The dual-band ommatidia common image equation was derived, and the matching requirement between ommatidia and the receiving system was established. The ommatidia optical system has working bandwidths of 0.38~0.78 μm and 8~12 μm, a focal length of 5 mm, a relative aperture of 1:3, and a field of view of 10°. The imaging position of the ommatidia system in both the bands is 2.92 mm. The angle between two neighboring center optical axes of the neighboring ommatidia is 4.016°, with 650 ommatidia, and the combined field of view is 90°.The receiving optical system has a focal length of 4 mm, a field of view of 80° and a relative aperture of 1:3. The ommatidia system and receiving system show good image quality, without any thermal effects in the temperature range of -40℃ to 60℃.
