Photopolarimeter
Subsystem
The Photopolarimeter Subsystem uses a 0.2 m telescope fitted
with filters and polarization analyzers. It covers eight wavelengths
in the region between 235 nm and 750 nm.
The experiment is designed to determine the physical properties
of particulate matter in the atmospheres of Jupiter, Saturn,
and the Rings of Saturn by measuring the intensity and linear
polarization of scattered sunlight at eight wavelengths
in the 2350-7500A region of the spectrum. The experiment
will also provide information on the texture and probable
composition of the surfaces of the satellites of Jupiter
and Saturn and the properties of the sodium cloud around
Io. During the planetary encounters a search for optical
evidence of electrical discharges (lighting) and auroral
activity will also be conducted.

instrument.
