Journal ArticleDOI
Design of an optical see-through head-mounted display with a low f-number and large field of view using a freeform prism
TL;DR: This paper presents an OST-HMD design using a wedge-shaped freeform prism cemented with a freeform lens, which serves as the near-eye viewing optics that magnifies the image displayed through a microdisplay.
Proceedings ArticleDOI
An optical see-through head mounted display with addressable focal planes
Sheng Liu,Dewen Cheng,Hong Hua +2 more
TL;DR: A see-through HMD with addressable focal planes utilizing a novel active optical element - a liquid lens able to address the focal distance of the HMD from infinity to the near point of the eye is presented.
Journal ArticleDOI
Design of an ultra-thin near-eye display with geometrical waveguide and freeform optics
TL;DR: Small thickness and light weight are two important requirements for a see-through near-eye display which are achieved in this paper by using two advanced technologies: geometrical waveguide and freeform optics.
Journal ArticleDOI
A Novel Prototype for an Optical See-Through Head-Mounted Display with Addressable Focus Cues
Sheng Liu,Hong Hua,Dewen Cheng +2 more
TL;DR: Both subjective and objective measurements suggest that the perceived depths and accommodative responses of the user match with the rendered depths of the virtual display with addressable accommodation cues, approximating the real-world 3-D viewing condition.
Patent
Optical see-through free-form head-mounted display
TL;DR: A see-through free-form head-mounted display including a wedge-shaped prism-lens having freeform surfaces and low F-number is provided in this paper. But this display is not suitable for head mounted displays.
