NOTE:
The profile is not corrected for tilt angle even if cloud heights are corrected.
2.2 Optical measurement
FIGURE 2-1. Principle of operation
2.2.1 Optical arrangement
The SkyVUE 8M uses a single lens design that increases optical signal-to-noise ratio, while
maintaining Class 1M eye safety by integrating larger optics into a compact package (see
(p. 8)). Half of the lens is used by the transmitter, and the other half is used by the receiver.
This design provides an alternative to traditional two lens or common-optics designs. The optical
isolation of traditional biaxial systems is maintained to increase detector sensitivity, while the low
overlap onset height of common-optics systems is incorporated to allow measurements at close
ranges.
2.3 Internal monitoring
The SkyVUE 8M monitors window contamination, key voltages and currents, internal
temperature and relative humidity, and other parameters relevant to its performance. Data
