Abstract

The invention discloses a contact lens type optical system and a head-mounted display equipped with the same. The contact lens type optical system is arranged between an image generating unit and human eyes, and comprises a lens, a light split assembly, a quarter-wave plate assembly and a polarization filter, wherein the lens is used for forming a preset focal length for light information of an image generated by the image generating unit; the light split assembly is used for enabling target light to enter an image receiver after passing through the lens back and forth for many times, and comprises a first light spliter located between the lens and the image generating unit and a second light spliter located between the lens and the human eyes; the quarter-wave plate assembly is used for adding a quarter wavelength of phase for transmission light; the polarization filter is used for shielding stray light from entering the image receiver, and the lens, the light split assembly, the quarter-wave plate assembly and the polarization filter are fitted together to form a contact lens. The head-mounted display comprises the contact lens type optical system and the image generating units arranged on the same optical axis. The contact lens type optical system and the head-mounted display equipped with the same, disclosed by the invention, have the characteristics of compactness, small volume, light weight, large field angle, large exit pupil diameter and good imaging quality.

Description

technical field [0001] The invention relates to a head-mounted display system, in particular to a contact lens-type optical system and a head-mounted display equipped with the optical system. Background technique [0002] Various modern electronic or optical systems are developing towards miniaturization and high performance. Head-mounted display is a newly emerging display system in recent years. It has a wide range of applications in multimedia communication, game entertainment, military training, industrial field control, medical treatment, virtual reality and augmented reality. Head-mounted display (English full name Head-Mounted Display, English abbreviation HMD) has entered people's lives, it brings users a strong sense of immersion and reality, and can bring subversive breakthroughs in human visual experience. Significant application and commercial value. [0003] The head-mounted display should be small in weight, small in size, comfortable to wear and large in fie...
