Abstract
Systems and methods for implementing a continuously monitoring safety system that tracks emission of light energy from the light source by measuring energy at various sampling points within image frames projected by a projector and estimating a highest energy for a pupil area of each of the image frames based on a subset of sampling points encompassed by the pupil area. The highest energy for each of the image frames is summed to generate a cumulative highest energy, which is compared to a predetermined threshold, and in response to the cumulative highest energy exceeding the threshold, adjusting an power output of the projector.
