Beam Modulators¶
Beam modulators are able to control laser intensity at high speeds to adjust illumination. Beam blanking is used for intervals where no data is collected (mirror turnarounds) to avoid overexposure of the sample. Beam modulation in ScanImage® is elaborated upon in the concepts section: Beams.
ScanImage® can control beam modulators via an analog control signal. The voltage of the control signal determines the beam power. Optionally a beam power feedback output can be used for calibration.
