Abstract:
A scanning projector includes an optical filter. The optical filter exhibits a variable attenuation as a function of position. The scanning projector may scan sinusoidally in at least one dimension. The variable attenuation of the optical filter compensates for brightness variations due to sinusoidal scanning.
