| abstract |
An intermediate image of the image of the LCD module 142 is deflected by the reflection mirrors M1 and M2 via the zoom / autofocus control system g and formed on the diffusion glass 131 via the relay lens b and the reflection mirrors M3 and M4. . The light beam diffused to about ± 20 ° by the diffusing glass 131 projects an LCD image on the retina of the eyeball through the eyepiece 132. One surface of the lens closest to the crystalline lens 2 of the eyepiece 132 has an aspherical shape made of a conic surface, and the conic coefficient of the conic surface is smaller than −1. As a result, an optical system with a viewing angle of 60 ° or more and less aberration can be obtained. |
