Abstract

The invention provides a plane symmetric imaging optical plate. The plane symmetric imaging optical plate comprises a first light-permeable substrate and a second light-permeable substrate which are arranged from top to bottom, and is characterized in that the first substrate is provided with a plurality of first reflecting surfaces, the second substrate is provided with a plurality of second reflecting surfaces which are orthogonal with the first reflecting surfaces, and divergent light arrives at the part above the first substrate after being reflected by the first reflecting surfaces and the second reflecting surfaces and is collected and imaged in a space above the first substrate. The plane symmetric imaging optical plate realizes twice reflection through staggered rectangular blocks or rectangular holes arranged on the first substrate and the second substrate, and the pixel density is enabled to be higher than that of similar technologies. In addition, the plane symmetric imaging optical plate has a low requirement for the machining accuracy for right angles of the rectangular blocks or rectangular holes is low, light is reflected only through the side wall, and the machining difficulty and the overall cost are reduced.

Description

technical field

[0001] The invention relates to the technical field of optical imaging components, in particular to a plane symmetrical imaging optical plate. Background technique

[0002] The planar symmetric imaging optical elements in the prior art are mainly used in display devices, where the divergent light emitted by a luminous object or an optically irradiated object is transmitted through an optical plate, reflected twice in the optical plate, and then can be compared with the luminous object or The optical plate that optically irradiates the object has a positional relationship, and converges the image at a plane symmetrical position. Among them, the micromirror array formed by arranging a plurality of concave unit optical elements or convex unit optical elements in an array has attracted attention in recent years. The unit optical element or the convex unit optical element has "two mutually orthogonal mirror surfaces" (a pair of adjacent light reflection surfaces f...
