Abstract

The embodiment of the invention provides a projection system, and belongs to the technical field of projection equipment. The projection system comprises a light beam generating device, a light beam processing device and an optical system, wherein the optical system is used for carrying out aberration correction of discrete wavelengths; wherein the optical system comprises at least three lenses, and at least one of the at least three lenses is a super lens; the light beam generation device is configured to generate an initial light beam suitable for the super lens, and the initial light beam comprises at least three narrow-band light beams with discrete wavelengths; the light beam processing device processes the initial light beam according to image information to be projected and then emits the initial light beam into the optical system, so that the optical system projects the initial light beam; the projection system at least satisfies: WD > = 100d; wherein WD is the working distance of the projection system; and d is the distance from the light beam processing device to the incident plane of the optical system. According to the projection system, the application of the super lens in the projection system is realized.

Description

technical field [0001] The present application relates to the technical field of projection equipment, and in particular, the present application relates to a projection system. Background technique [0002] Correcting chromatic aberration through optical lenses is one of the important means for the projection system to improve the imaging quality. With the development of science and technology, the demand for miniaturization of projection systems is increasing day by day, and the loss of image quality during the miniaturization process seems to be unavoidable. [0003] In the prior art, chromatic aberration correction is usually performed by increasing the number of lenses in the projection system to pursue higher imaging quality. Generally, the larger the number of lenses, the larger the lens volume and the higher the image quality. [0004] However, the miniaturization of the projection system in the prior art is limited by the number of lenses and the volume of the len...
