Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] An embodiment of the present invention provides an optical field conversion device.

[0032] see Figure 1 to Figure 4 , the light field conversion device includes a first lens 100 , a second lens 500 and a field lens 200 .

[0033] It should be noted here that the first lens 100 is used to compress the divergence angle of the light beam and perform field curvature correction and distortion correction on the light beam, and the second lens 500 is used to perform field curvature correction and distortion correction on the light beam generated by the first lens 100 correction.

Abstract

The invention belongs to the field of laser display, in particular to a light field conversion device and laser display equipment. The light field conversion device comprises a first lens, a second lens and a field lens, wherein the first lens, the field lens and the second lens are sequentially arranged along a light path, and a first focal plane of the light field conversion device is arranged between the first lens and the field lens. Based on the structural design of the invention, the total length of the whole optical system is shortened, the reduction of the space volume is facilitated during space folding, and the design of the whole machine and the miniaturization of products are facilitated.

Description

technical field [0001] The invention belongs to the field of laser display, and in particular relates to a light field conversion device and a laser display device. Background technique [0002] With the continuous development of laser technology, laser display technology and equipment have entered people's field of vision one after another. At present, the mainstream laser display technology is mostly based on projection display technology, using laser light source to replace conventional LED light source or light bulb, with high brightness, large color domain, long life and low power consumption. In the laser projection technology, the laser shimming illumination problem of the spatial light modulator is involved, that is, it is necessary to ensure that the surface light field of the effective working area of ​​the spatial light modulator is uniform and the illumination angle meets the requirements. For this purpose, a light field conversion device is required to realize i...
