Folding and super hybrid pancake optical lens

The invention discloses a folding and super hybrid pancake optical lens, and relates to the technical field of optical display. Two planes of the refraction and reflection lens and the super lens are oppositely arranged, and a 1/4 phase delay piece is arranged between the refraction and reflection lens and the super lens; light emitted by an image source passes through the polarization selection sheet and is filtered into linearly polarized light, the linearly polarized light directly penetrates through the refraction and reflection lens, penetrates through the 1/4 phase delay sheet and meets the plane side of the super lens, the light is reflected back and passes through the 1/4 phase delay sheet again, and at the moment, the linearly polarized light changes in phase, penetrates through the plane side of the refraction and reflection lens and then meets the curved surface side of the refraction and reflection lens. The curved surface of the turn-back lens is plated with a thin film through which polarized li
