Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] The relay optical system provided by the invention is used for the helmet display. Such as figure 1 As shown in , the image space is on the left of the relay optical system, and the object space is on the right of the optical system. The relay optical system includes a first lens L1, a second lens L2, a third lens L3, a fourth lens L4, a fifth lens L5 and a sixth lens L6 arranged on the same optical axis in sequence from the image side to the object side, wherein, The third lens L3 and the fourth lens L4 form a cemented lens group. Therefore, in this optical system, the surface close to the image side of the lens is the first surface, and the surface close to the object side is the second surface, and the order of the lenses in the optical system is according to the direction from the image side to the object side Arranged sequentially. In addition...

Abstract

The invention relates to a relay optical system for a head display. The relay optical system comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens arranged on the same optical axis in sequence from the image to the object, wherein the third lens and the fourth lens form a cemented lens set. The relay optical system only comprises six lenses, and does not involve other equipment and devices, so the system is simple and compact in structure, small in size and light, and is favorable for miniature design; and the optical system has the advantages of large relative aperture, wide spectra and large view field, has higher reliability, can effectively correct the aberration, and thus has excellent imaging quality.

Description

technical field [0001] The invention relates to a relay optical system for head-mounted displays, belonging to the technical field of head-mounted displays. Background technique [0002] A helmet-mounted display (HMD, Head Mounted Display) is a small display device that is fixed on the helmet and generates visual images for the user. Because the helmet-mounted display system has the ability to guide radar, laser, forward-looking infrared and other detection equipment to quickly align with the target, it has become the advanced equipment of various arms. This comprehensive electronic display device composed of electronic components, display components, and controllers can Information such as flight parameters, aiming attack, and self-inspection is projected to the display device on the helmet through optical components in the form of images and characters. The helmet display technology has shown great application value and development potential in many fields. Among them, t...
