Abstract:
1. A multi optical-route Head Up Display (HUD), comprising: at least an image display unit, to generate at least two distinct input images; a plurality of separately addressable relay lenses, to independently adjust a respective refraction angle of one of said input images, and receive and transmit said input images; at least a virtual image generation unit, and said input images outputted from said addressable relay lenses pass along intersecting optical routes to converge toward said virtual image generation unit, so that said virtual image generation unit receives said input images and produces a plurality of virtual images; and a plurality of transmission mirrors, to receive said virtual images and reflect them into a converging large area virtual image for concurrent viewing by two eyes of a user, wherein said transmission mirror is a planar plate of high reflection optical thin film, with its transmission rate between 70% and 75%, and its reflection rate between 25% and 30%, and said transmission mirrors are fixed on a rotatable mechanism, and said rotatable mechanism is disposed on a rotation actuation mechanism, and said rotatable mechanism is rotated around a horizontal axis in a clockwise or a counterclockwise direction, and said rotation actuation mechanism is rotated around a vertical axis in a clockwise or a counterclockwise direction, such that a display angle of said transmission mirrors is selectively adjusted based on height and seating gesture of said user.
