Scanner mechanism

The 20-Hz voice coil resonance scanner oscillates over the short x-axis of the glass slide and the data are acquired up to 22-mm amplitude. The shorter the amplitude the longer can be the dwell time for data acquisition without compromising speed but gaining the advantage of getting more photons to improve the signal-to-noise ratio (SNR) , which can be selected in acquisition software. The transport table holding the sample (e.g. slide adapter) is moved slowly in the y-direction in steps of 4 to 40 |m depending on the resolution selected.
