摘要: 针对海面监视的需要,设计一型制冷型红外热像仪的光学系统,其探测能力要求为对500 t(大于10 m×10 m)以上海面舰船探测距离不小于23 km。首先确定红外探测器;然后通过探测距离分析计算确定其焦距值、变倍比、通光口径等参数;根据上述参数运用Zemax光学设计软件进行光学系统详细设计,并对其成像质量和像差进行分析。通过外场实验验证了其探测能力,证明了其设计的合理性。

Abstract: For the needs of maritime surveillance, an optical system of refrigeration infrared thermal imager is designed, for which the detectability is not less than 23 km for an over 500t level sea surface ship (greater than 10 m×10 m). The infrared detector is determined. The parameters such as focal length, zoom ratio and aperture are determined by the distance analysis. The detailed design for the optical system is performed according to the above parameters using Zemax software optical design. The imaging quality and aberration is analyzed. The detectability is verified by field experiment, which proves the rationality of design.

Key words: maritime surveillance, infrared thermal imager, sea ships, detectability, optical systems, optical design
