See Photon Counting for more information.


More information about Photon Counting can be found on the Photon Counting concept page.

Photon Counting Controls

Uniform Pixel Bin SizeDisables the geometry correction for the non-uniform resonant scanning speed (see Line Formation)

Photon Counting Controls - Integration Mode


Differentiate Before IntegrationApply centered differentiation on signal for photo current integration
Absolute Value Before IntegrationTake the absolute value on signal for photo current integration
Enable Integration ThresholdIgnore any values below threshold for photo current integration
Integration ThresholdValue of integration threshold (in ADC units)
Disable Mask AveragingDisables the division after sample binning (see Line Formation).

Photon Counting Controls - Photon Counting Mode


Configure Photon DiscriminatorShows the photon discriminator GUI
Show Photon HistogramShows the photon histogram
Photon Selection MaskFor time correlated photon counting; Binary mask that selects photons after laser pulse used to display in channel
Disable Mask AveragingDisables the division after sample binning (see Line Formation). Should be ON for photon counting.
