Abstract
Embodiments of this application relate to the technical field of optical design, and disclose a method for adjusting field of view angle applied to a waveguide plate in a near-eye display equipment, the waveguide plate forms a tilt angle relative to horizontal direction of human face, the method firstly acquires refractive index, bottom angle of the waveguide plate and a required field of view angle, then calculates the tilt angle of the waveguide plate according to the refractive index and bottom angle of the waveguide plate and the field of view angle, and finally, adjusts the tilt angle to make sure the near-eye display equipment with the field of view angle; the method disclosed by this application enables the waveguide plate to realize low refractive index and large field of view angle at the same time, and features better imaging, lower cost and better stability.
