In order to make a comprehensive evaluation on a head mounted display (HMD)
a simple and feasible testing method is proposed and an optical system for the test is specially designed. According to the requirement of pupil engagement for the HMD and the testing system
a structure of eyepiece is adopted in the optical design
and a plastic aspheric lens is used to realize the distortion-free property. The designed optical system has a field of view of 50?
a pupil size of 4 mm and a distortion less than 0.1%. It can keep high performance when the testing HMD is with diopter from -4 D to 3 D. The analyses on the design show that the evaluation system can satisfy the evaluation requirement of HMD with various diopters.
