Resonant Scanning

A resonant scanner is scanning device that oscillates the beam-steering mirror in a sinusoidal motion of controllable amplitude. The phase of the scanner cannot be controlled, but it can be accounted for.

Having a resonant mirror in the scanhead allows for higher frame rates than is usually possible with galvanometric scanners, but its implementation takes a few more considerations that the user should be familiar with.

Read the following pages to learn about how ScanImage® uses resonant mirrors and the settings that the user should modify to obtain images of desired quality.
