摘要:
论述了通过景深分析和无热化设计实现无调焦光学系统的原理。基于长波大面阵(640×512)非制冷探测器,设计了同时适应物距变化(15 m~100 m)及温度变化(-55℃~+70℃)的无热红外光学系统,焦距33 mm,F数1.3。设计结果表明,该系统在宽温度范围内具有良好的消热差性能,并且完全覆盖目标物距范围,从而实现了无调焦的要求,提高了系统操作性和可靠性。
Abstract:
The theory of optical system without focusing mechanism based on the depth of field and athermalization is discussed in this paper. An athermal optical system working under temperature of ? ? ?-55℃~+70℃ and object distance of 15 m~100 m is designed on long-wavelength uncooled infrared detector (640×512). The EFFL is 33 mm, and the F number is 1.3. Results proved that this system posses good athermal ability in wide temperature range,and meet the requirements of object distance. Consequently,this system reached good image quality without focusing mechanism, the operatability and reliability have been improved.
