摘要

为满足便携式投影仪的市场需求, 设计了一种基于LED微型阵列的投影系统。该系统由显示单元和投影物镜构成。采用尺寸为12 mm×9 mm的自发光LED微型阵列作为系统的显示单元, 利用光学设计软件设计了投影物镜。投影物镜采用反远距光学结构, 全视场角为80°, 焦距为8 mm, 属于强光、广角镜头。在空间频率20 lp/mm处, 该物镜的调制传递函数大于085, 畸变小于2%, 符合投影系统的设计要求。该投影系统具有体积小, 结构简单, 投影效果好, 易加工等诸多优势, 可为第三代投影技术的发展提供参考。

Abstract

In order to meet market demand for portable projectors, a projection system using an LED micro array and composed of a display light source and an imaging system is designed. The size of the self-luminous micro-LED array is 12 mm×9 mm. This micro-LED array is used as the light source. A projection lens suitable for the light source is designed by using Zemax software. The projection adopts an anti-distance optical structure with a full field-of-view angle of 80 degrees and a focal length of 8 mm. This projection uses a strong-light and wide-angle lens. The modulation transfer function of the objective lens is greater than 085 at a spatial frequency of 20 lp/mm and its distortion is less than 2%, which meets the design requirements of the projection system. The projection system has many advantages, such as a small size, a simple structure, good projection, easy production, etc.. It can also provide reference for the development of third-generation projection technology.
