1. A wearable heads-up display (“

  • WHUD”

    ) comprising;

    a support structure that in use is worn on a head of a user;

    a transparent combiner carried by the support structure, wherein the transparent combiner is positioned within a field of view of an eye of the user when the support structure is worn on the head of the user;

    a laser projector carried by the support structure, the laser projector comprising;

    at least one laser diode to generate laser light;

    at least one controllable mirror positioned to receive the laser light from the at least one laser diode and controllably orientable to redirect the laser light towards the transparent combiner; and

    at least one anamorphic optical element positioned in an optical path of the laser light in between the at least one laser diode and the transparent combiner, the at least one anamorphic optical element oriented to shape a spot of the laser light to compensate for an astigmatic effect of at least the transparent combiner on the laser light.
