Abstract
A head mounted display and a multiple depth imaging apparatus thereof are provided. The imaging apparatus includes a beam splitting device, a first display, a second display, a third display and a lens set. The beam splitting device has a first reflective surface, a second reflective surface and a transmissive surface. The first display projects a first image to the first reflective surface. The second display projects a second image to the transmissive surface. The third display projects a third image to the second reflective surface. The lens set is disposed between the beam splitting device and a target area. The first image, second image and third image are respectively imaging on a first imaging surface, a second imaging surface and a third imaging surface, and distances between the target area and the first, second and third imaging surfaces are different.
