Abstract
A resonant scanning mirror includes a sensor to provide position information. A parameter estimation circuit estimates parameters from the position information. The parameter estimation circuit includes wideband analog circuits that have poles far removed from the resonant frequency of the scanning mirror. The parameter estimation circuit also includes an analog-to-digital converter that samples at a high sample rate, and digital filters that exhibit near perfect linearity.
