Abstract: The techniques disclosed herein provide methods, devices, and systems to compensate the drive waveform to a slow-scan mirror in a laser beam scanning (LBS) display device. The slow-scan controller generates the drive waveform, which is combined with feedback and coupled to the input of a notch filter in the control loop. Ripple in the slow-scan mirror trajectory, which occurs as a consequence of mismatches between the notch frequency of the notch filter and the resonance of the slow-scan mirror, is effectively suppressed in real time by an adaptive notch compensator. Consequently, the described compensation scheme allows for relaxed notch filter design criteria with high tolerance and mitigation of ripple is achieved at reduced cost. The parameters, logic and blocks of the adaptive notch compensator scheme may be time-domain or frequency domain solutions that are implemented, in hardware, software or combinations thereof.

Abstract: A laser beam display device that can dynamically control the resonant frequency of a mirror is provided. The increase the reliability of a device by controlling the resonant frequency of a mirror instead of requiring components of a display device to react to changes in the resonant frequency of a mirror. A controller can drive a mirror with an input signal, receive a signal or data indicating a target resonant frequency, and bias the input signal to control the resonant frequency of the mirror. In some embodiments, the controller can also receive a feedback signal from a mirror indicating a current resonant frequency. The controller can also bias the input signal to increase or decrease the current resonant frequency. By dynamically controlling the resonant frequency of a mirror, a device can minimize any difference between the current resonant frequency detected in a feedback signal and the target resonant frequency.

Abstract: Techniques are described herein that are capable of adjusting a notch frequency of an adaptive notch filter (“filter”) to track a resonant frequency of a slow scan MEMS mirror (“mirror”). For instance, an adaptive feedback may be configured to determine one or more resonant frequencies of the mirror based at least in part on a frequency response of an output signal that is proportional to movement of the mirror. The adaptive feedback may be further configured to adjust at least one notch frequency of the filter to track at least one respective resonant frequency of the mirror. The filter may be configured to modify a magnitude of a frequency response of a combination of the filter and the mirror to be substantially constant by suppressing the at least one notch frequency in a frequency response of the mirror.
