Abstract
A head-up display includes, inside a housing, an image-generating device configured to generate a light beam which passes through an optical output element, a first reflector configured to reflect the light beam as an intermediate beam, and a second reflector configured to reflect the intermediate beam as an output beam. The housing includes an opening closed by a window through which the output beam passes. The propagation of light through the optical output element, in reflection on the first reflector, in reflection on the second reflector, and through the window, defines an optical path with two ends. Two elements from the optical output element, the first and second reflectors, and the window are provided, respectively, with a first and second spectral filter. The first and second spectral filter are configured to prevent the propagation of a spectral component of the light beam.
