为了辅助静脉穿刺及相关的医疗操作，设计了一款基于投影式头戴显示器（ HMPD）的静脉显像系统，其光学系统由近红外成像系统和穿透型HMPD构成。利用光学设计软件ZEMAX优化设计近红外成像系统，使其具有F／2.6的大数值孔径，有利于弱反射红外光的收集成像。穿透型HMPD采用与近红外成像系统相同的光学结构，有利于简化系统的加工装调。设计结果表明，近红外成像系统成像质量优异，分辨率达到QXGA （2048×1536）。穿透型HMPD具有18 mm的大出瞳直径及25 mm的大出瞳距离，场曲小于0.03 D，畸变小于0.32％，达到QXGA分辨率显示模式。与现行的静脉显像系统相比，本显像系统结构简单紧凑、佩戴舒适，且具有超高分辨率，是一款适用于辅助医疗的目视系统。

In order to assist venipuncture and related medical operations , a novel vein imaging device based on head-mounted projective display ( HMPD) is designed .The correspondent optical system consists of near-infrared imaging system and see-through HMPD .With the help of optical design software ZEMAX , the near-infrared imaging system has a large numerical aperture with F number of 2.6 , which is extremely conducive to receive and to image the weak reflected near-infrared light .The structure of the optical system of HMPD is same as that of near-infrared imaging part , which is conducive to simplify the processing and assembly .The results indicate that the performance of imaging system is excellent and the resolution is up to QXGA (2 048 × 1 536).The see-through HMPD possesses an 18 mm exit pupil and a 25 mm eye relief, with the field curva-ture less than 0.03 D, the distortion less than 0.32%and the resolution up to QXGA .Compared with the cur-rent vein imaging device , the proposed system is characterized by compact structure , comfort wearing and ul-trahigh resolution , which is suitable for assistant tools in venipuncture techniques .
