| 英文摘要 | Systems, devices, and methods for beam shaping in wearable heads-up displays (WHUD) with laser projectors are described. A WHUD includes a support structure carrying a laser projector and an eyeglass lens with a transparent combiner. The laser projector includes at least one laser diode, at least one anamorphic optical element, and a controllable mirror having a reflective area. The at least one laser diode generates laser light having a spot area with at least one dimension being smaller or larger than the dimensions of the reflective area of the controllable mirror. The at least one anamorphic optical element anamorphically reshapes the spot area such that the second spot area has approximately the same dimensions as the controllable mirror. The controllable mirror scans the reshaped laser light over the transparent combiner, which redirects the light, creating a focused image at the eye of the user with minimal loss of laser light. |
