摘要

微型投影仪具有体积小、便于携带的特点,因此,在商业领域和家庭娱乐等领域具有广泛的应用。LCOS微型投影物镜具有共轭距短,视场角大等优点,是微型投影仪的重要研究方向。文中采用非球面结构,设计一款短焦距、大视场的投影物镜,该系统焦距为7.4mm,全视场角为85°,最大畸变小于0.5%,在空间频率43lp/mm处的传递函数大于0.5。
        The micro projector has the advantages of small volume,easy to carry,therefore,it is widely used in the field of business,home entertainment and so on.LCOS micro projection lens has the advantages of short conjugate distance,large field of view and so on, It is an important research direction of micro projector.In this paper, the non spherical structure is adopted to design a short focal length,large field of view of the projection lens,the focal length of the system is 7.4mm,the full field of view angle is 85°,the maximum distortion is less than 0.5%,the transfer function is greater than 0.5 at the spatial frequency of 43lp/mm.
