Abstract
One example provides a method enacted on a scanning display device comprising an illumination source, and a scanning mirror system including a sense circuit coupled to a scanning mirror. The method comprises operating the scanning mirror system using a drive signal while operating the illumination source to thereby project an image, obtaining a control parameter based at least upon an output of the sense circuit, and comparing the control parameter to a noise threshold condition. The method further comprises, when the control parameter does not meet the noise threshold condition, continuing operating the scanning mirror according to the drive signal. The method also comprises, when the control parameter meets the noise threshold condition, adjusting the drive signal to form an adjusted drive signal to change a trajectory of the scanning mirror.
