摘要: |
为解决现有车载抬头显示系统投射的影像尺寸较小,其投影图像所能显示的信息有限的问题,本发明提供了一种车载抬头显示系统,包括显示屏组件和三反式光学组件,其中,所述三反式光学组件包括在光路上依次设置的变倍镜组件、像质补偿镜组件和前挡补偿镜组件;所述变倍镜组件包括变倍镜片、以及变倍镜片调焦组件;所述像质补偿镜组件包括像补镜片、以及像补镜片调焦组件。本发明提供的车载抬头显示系统,可实现连续变焦,对投影图像进行几倍甚至十几倍的放大,并能保证像面的位置不变;且其像面质量稳定,不因其被放大而模糊或者变形;在十分有限的空间里面为驾驶员提供丰富的信息;为丰富车载抬头显示系统的使用功能提供技术上的保证。 |
摘要(英文): |
A projector for HUD includes a displaying component (1) configured to project an image, and a three-mirror optical device (10) configured to reflect the image onto a front windshield (5) which reflects the image to a driver' s eyes. The three-mirror optical device (10) comprises a zoom lens assembly (2) having a zoom lens (21) for zooming in/out the image projected by the displaying component (1), and an image quality compensation lens assembly (3) having an image quality compensation lens (31) for compensating for an image quality distortion caused during a change of the focus of the zoom lens(21), and a front windshield compensation lens assembly (4), configured to compensate for a distortion caused by the front windshield (5). A first and a second focus adjusting component (22, 32) are configured to adjust the focus of the zoom lens (21) and the focus of quality compensation lens (31), respectively. |
