diameter. - FSSP-100
- Forward Scatter, Ranges (selectable) 1.8 mm,
1-16 mm, - 1-32 mm, or 1 50 mm diameter.
- APS
- Time of flight Range 0.6 to 10 mm.
- CAPS
- Forward Scatter Range 0.5 50 mm diameter
- Backscatter Range 1 to 120 mm diameter
- Occultation Range 25(?) 1550 mm diameter
2Probe Calibration (CAPS)
Backscatter response
Forward scatter response Horizontal lines are
channel boundaries i.e., pulse heights in volts
3Probe Calibration (PCASP/FSSP)
FSSP response
PCASP Response The solid curves are
modelled responses for different refractive
indexes
4Data reduction
Uncertainties in inversion from measured
pulse height to diameter for the CAPS-forward
scatter Probe.
