A multi-focus physiologic sensing device for condensing light is disclosed, comprises a multi-focus condenser has one first ellipse reflection member, and one second ellipse reflection member is arranged at an end of the first ellipse reflection member. The first ellipse reflection member has a first focus point thereon. The second ellipse reflection member has two second focus points thereon. A boundary between the first ellipse reflection member and the second ellipse reflection member has a first confocal point. Two lighting elements are respectively arranged on the two second focus points to generate light sources, that focus light on the first confocal point through the second ellipse reflection member, and then the detected object reflects the detected light source back to the first confocal point. Then, the detected light source is passes through the sensor from the first focus.

Multi-focus physiologic sensing device for condensing light

A head-up display device comprises a reflective mirror mounting bracket having an accommodation space; a reflective mirror arranged on the reflective mirror mounting bracket, receiving a real image and reflecting the real image to generate a reflected image; and a concave imaging mirror mounting bracket accommodating a concave imaging mirror, wherein the concave imaging mirror is coated with an antireflection film on one side and coated with a semi-transmitting film on the other side, reflects the reflected image of the reflective mirror and presents a distant magnified virtual image. The present invention is characterized in a small size; no need to install the device inside the instrument panel system; directly using an existing display device to generate a distant magnified virtual image; and easiness for users to install the device.

Head-up display device

An image-partitioned display device for virtual image is disclosed. The display device comprises an image display unit, a refractive element, and a virtual image generation module. The refractive element is disposed between the image display unit and the virtual image generation module. Firstly, the image display unit generates at least one image, and then the refractive element refracts and partitions the image into a plurality of sub-images. Finally, the virtual image generation module receives lights of the sub-images to generate a large area virtual image or a plurality of enlarged virtual images. A volume of the virtual image generation module is reduced and all kinds of display information are provided by the image-partitioned technology.
