Problems solved by technology
[0003] The purpose of the present invention is to provide a continuous zoom optical system for head-mounted equipment, which adopts the method of moving the lens longitudinally to zoom, and solves the problem of not being suitable for myopia and hyperopia patients, small field of view, poor imaging quality, and the gap between two lenses. Lateral relative mechanical movement needs to occupy a large space and other issues

The invention relates to an optical system capable of realizing continuous zooming for a headset device. The optical system is characterized by comprising a display, a display supporting body, a lens I, a lens II, a lens II rear cover, a lens III, a mobile lens splitting barrel, a lens VI, a primary lens barrel and a lens V, wherein the display is fixedly connected to the display supporting body; the display supporting body is fixedly connected with the primary lens barrel; a split lens does left-right motion in the primary lens barrel via a driving mechanism; the lens V, the lens II and the lens I are and fixedly connected to the inner part of the primary lens barrel from left to right sequentially; the lens III and the lens VI are fixedly connected to the inner part of the lens splitting barrel. By longitudinally adjusting the lens for zooming, the device can obtain a large view field angle and excellent imaging quality; longitudinal adjustment of the lenses occupies less space and needs a sample motion mechanism, so that the size and the weight can be reduced, and a wearer feels more comfortable.
Description
technical field [0001] The invention relates to the technical field of virtual reality, in particular to a continuous zoom optical system for a head-mounted device. Background technique [0002] At present, patients with myopia and hyperopia need to wear glasses and then wear virtual reality equipment, which is very inconvenient. Most of the virtual reality devices on the market cannot zoom in order to adapt to myopia and hyperopia patients, and a few virtual reality devices that can zoom use the method of moving the lenses laterally to achieve zooming. Laterally moving lenses have disadvantages such as small field of view, poor imaging quality, and relatively large space required for lateral mechanical movement between the two lenses. Contents of the invention [0003] The purpose of the present invention is to provide a continuous zoom optical system for head-mounted equipment, which adopts the method of moving the lens longitudinally to zoom, and solves the problem of ...
