Electronics and Computer

Photomultiplier tubes in photon counting mode detect the backscatter signal. Data is time resolved in 100 ns bin widths, resulting in 15 m vertical resolution over 2333 data bins. A total of 8192 data bins are available for data acquisition among the various detector channels. System functions are maintained by an embedded Intel i960CA processor.

The system is monitored by a Sun Sparc II workstation which also stores and displays the raw data. Data points are displayed for a given polarization in a 4000 shot average, which allow real-time observation of the atmosphere as it is advected over the instrument.
