ADVANCED OPTICAL DESIGN AND MANUFACTURING TECHNOLOGY AND ASTRONOMICAL TELESCOPES AND INSTRUMENTATION(2016)
摘要
A single view-point catadioptric long infrared panoramic lens was designed with codeV. The system consists of a hyperboloid mirror and a conventional perspective imaging lens. The hyperboloid mirror enables the lens to obtain a large field of view, the conventional perspective imaging lens projects the virtual image formed by the mirror group onto the detector. The effective focal length is 1.4mm, the relative aperture is 1:1, field of view is +/- 10 degrees similar to +/- 90 degrees in vertical direction and 360 degrees in horizontal, the wavelength spectrum is 8-12 mu m, only Znse and Ge were used in this system. The lens has the characteristics of single view-point, large field view and getting perspective image straightly. Result shows that the modulation transformation function at 17/mm is greater than 0.7, which proves that the image quality of the optical system is good.
