Abstract

The invention discloses an optical system and a virtual reality device having the same. The optical system sequentially includes a display unit, a beam splitter, a first lens, a first phase retarder, a second lens, a polarizing reflector, and an outlet along the light transmission direction. Pupil surface; the first lens includes a first surface close to the display unit and a second surface close to the second lens; the second lens includes a third surface close to the first lens and a second surface close to the first lens The fourth surface of the pupil exit surface; the optical system satisfies the following relationship: wherein, Φ1 represents the transmission power of the first lens, and Φ2 represents the transmission power of the second lens; the present invention provides a projection The optical system and the projection device with the same are used to solve the problem that the large size of the projection optical system affects the carrying and use of the user.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical system and a virtual reality device having the same. Background technique [0002] In the field of virtual reality technology, in order to achieve the design requirements of large field of view and small volume, the optical system of virtual reality equipment is usually designed in the form of folded optical path. The first reflection occurs, the parameters of the optical components in the actual optical path are different from the theoretical values, and the difference in the incident angle and the wavelength of the light in the actual optical path will affect the characteristics of the optical components, so the optical system will have serious ghosting problems, thus Affect the user's observation of images in the virtual reality device. Contents of the invention [0003] The present invention provides an optical system and a virtual reality device with th...
