Problems solved by technology

[0003] Fan Haiying used the eye model to replace the human eye optical system, and designed a projection helmet objective lens based on the eye model, which corrected the aberration of the eye model, but the structural parameters of the eye model are the statistical average of many human eyes, not the helmet wearer. The structural parameters of the eye optical system, so the aberration of the eye model is not the aberration of the helmet wearer's eye optical system, and the helmet objective lens designed in this way does not really correct the aberration of the helmet wearer's eye optical system
In order to correct the aberration of the helmet wearer's eye optical system in the design of the projected helmet objective lens, the structural parameters of the helmet wearer's eye optical system mu

Example Embodiment

[0015] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, a projection helmet objective lens design method for correcting aberrations of the helmet wearer’s eye optical system of the present invention includes a projection helmet objective lens 11, a beam splitter 13, a retroreflective screen 15, and a phase plate that replaces the helmet wearer’s eye optical system 17 and the ideal lens 18; the phase plate 17 has the same aberration as the helmet wearer’s eye optical system, and the phase plate 17 can be easily measured by the existing Hartmann-Shaker wavefront sensor. The ideal lens 18 has no aberrations but has the same refractive power as the optical system of the helmet wearer’s eye, and the ideal lens 18 can be used to detect the total axial axis of the helmet ...

Abstract

The invention discloses a design method of a projection type helmet objective lens capable of correcting eye optics system aberration. The method is characterized in that in helmet objective lens design, a phase plate with identical aberration with the eye optics system of a helmet wearer and an ideal lens are used to replace the eye optics system of the helmet wearer, the aberration of the eye optics system of the helmet wearer is corrected, and the helmet wearer is allowed to obtain high-resolution and clear information image of the outside world on the retina through a helmet. In addition, the method solves the problem that the structural parameters of the eye optics system of the helmet wearer are hard to acquire.

Description

technical field [0001] The invention relates to the field of projection helmet objective lenses, in particular to a design method of a projection helmet objective lens for correcting eye optical system aberrations. Background technique [0002] The external information image presented on the projected helmet microdisplay enters the human eye after passing through the helmet objective lens, beam splitter and reflective screen, and is imaged on the retina of the human eye through the human eye optical system, so that the human eye can see the external information. Therefore, the external information image presented on the projection helmet microdisplay will pass through the helmet objective lens and the human eye optical system. First of all, if there is aberration in the objective lens optical system of the projection helmet, the imaging quality will be reduced, that is, the resolution of the image will be reduced, and the image will become blurred and unclear. Secondly, the...
