Design and Study of the Dome-screen Projector Optical System
球幕投影光学系统的设计与研究

An optical system of Dome-screen projector which plays important roll in the pilot-training process was proposed.The lens system adopted the Reverse-Telephoto configuration which had an effective focal length of 5.5mm,an F-number of F/4 ,a field of view of 175°,and a working wavelength in the range of visible spectrum.A discussion about the relationship between the screen radius and the field curve was presented to explain why this system had an advantage in reducing the field curve.A relatively convenient method of choosing the appropriate screen radius was given at the end of the discussion.
