resonant scanning

A high-speed scanning approach that has been applied to point-scanning confocal microscopy where the fast scan (X) is performed using a fast resonant-scanning galvanometric mirror driven by a sinusoidal signal and the slow scan (Y) is performed using a typical linear galvanometer mirror driven by a sawtooth signal.

Resonant Scanning in Laser Confocal Microscopy

In order to acquire images on the faster timescales often required by live-cell imaging, laser scanning confocal microscopes must be re-engineered to incorporate advanced scanning scenarios that enable the beam to be raster-scanned across the specimen at higher speeds. To overcome the inherently slow speed of traditional confocal microscopes, several manufacturers have introduced instruments equipped with resonant scanning mirrors that are capable of gathering images at 30 frames per second or higher, including Nikon's A1R HD25 system.
