Abstract
A scanning projector includes a brightness compensation component. The brightness compensation component modifies pixel brightness as a function of instantaneous scan phase of a sinusoidally scanning mirror. The brightness compensation component uses different brightness compensation functions based on whether the instantaneous scan phase is above or below a threshold. The threshold may correspond to a knee of a maximum laser power limit curve.
