Head up display for vehicle
A head up display for a vehicle including an imaging device configured to emit first linearly polarized light in a first direction and second linearly polarized light in a second direction perpendicular to the first direction; a polarizing reflection mirror through which the first linearly polarized light is transmitted and from which the second linearly polarized light is reflected; a second reflection mirror spaced apart from the polarizing reflection mirror and at which the first linearly polarized light transmitted through the polarizing reflection mirror is reflected to the polarizing reflection mirror; and a first reflection mirror spaced from the polarizing reflection mirror and configured to reflect the second linearly polarized light reflected from the polarizing reflection mirror to a windshield of the vehicle to produce a first image having a first length from the windshield, and to reflect the first linearly polarized light reflected from the second reflection mirror and transmitted through the polarizing reflection mirror to the windshield of the vehicle to produce a second image having a second length from the windshield different than the first length.
