1. A light projection system comprising:

  • a projection subsystem configured at least to project an image;

    a light source subsystem configured at least to generate light directed along an image path leading to the projection subsystem; and

    a light-intensity-measurement subsystem configured at least to determine an intensity of the light and comprising a light-intensity sensor in the image path;

    wherein the light is stereoscopic light comprising a left-eye light beam and a right-eye light beam that follow a same path along the image path, and wherein the light-intensity sensor is configured at least to measure light intensity during a blanking period between the left-eye and right-eye light beams.
