MICROMIRROR RESONANCE SUPRESSION USING CONFIGURABLE FILTER - A simplified explanation of the abstract

This abstract first appeared for US patent application 17827413 titled 'MICROMIRROR RESONANCE SUPRESSION USING CONFIGURABLE FILTER

Simplified Explanation

The patent application describes a method for configuring a micromirror to suppress its resonance.

• The micromirror is subjected to different actuation frequencies and its response is measured.
• The resonant frequency of the micromirror is determined based on these measurements.
• Notch filter parameters are selected based on the determined resonant frequency.
• The notch filter is then configured with the selected parameters to suppress the resonance of the micromirror.

Original Abstract Submitted

The configuring of a micromirror to suppress a resonance of the micromirror. As part of the configuring process, the micromirror is subjected to multiple actuation frequencies, and the micromirror response is measured in response to at least some of these actuation frequencies. A resonant frequency of the micromirror is then determined using at least some of the measured mechanical responses. Then, depending on this determined resonant frequency of the micromirror, notch filter parameters are selected. There is more than one possibility for notch filter parameters, where the selected possibility depends on the determined resonant frequency. The notch filter is then configured with the selected notch filter parameters.
