FIELD: optical equipment.
SUBSTANCE: invention relates to the technique of projection systems for displaying information and can be used for on-board indicators on the windshield of a collimator type. The system contains an image source located in the focal plane of the power combiner, which is inclined to the horizontal axis of sight. According to the first version of the invention, the image aberration corrector is an optical refractive component that is located in close proximity to the surface of the image source and is made in the form of a wedge-shaped element with spherical or aspherical surfaces. According to the second version of the invention, the image aberration corrector is an optical reflective component that is located between the image source and the power combiner and is made in the form of a convex mirror with spherical or aspherical surfaces. The curvature parameters of the surfaces of the wedge-shaped element and the mirror ensure the introduction of aberrations into the image that are the reverse of those introduced into the image by the power combiner.
EFFECT: improving the image quality by simplifying the design of the collimator indicator system.
