OCULAR OPTICAL SYSTEM AND HEAD MOUNTED DISPLAY
An ocular optical system (EL) has a Fresnel lens (L1) having a plurality of Fresnel zones (FR) formed on a lens surface on the observation object side. The plurality of Fresnel zones (FR) is concentrically arranged side by side along an aspherical surface that is rotationally symmetric about the cen...

| Zusammenfassung: | An ocular optical system (EL) has a Fresnel lens (L1) having a plurality of Fresnel zones (FR) formed on a lens surface on the observation object side. The plurality of Fresnel zones (FR) is concentrically arranged side by side along an aspherical surface that is rotationally symmetric about the central axis of the Fresnel lens (L1), and the plurality of Fresnel zones satisfies the following conditional expression: 0 < PAE1 / PAC1 |
